Jamal Khashoggi's son glared at the Saudi royal blamed for his father's death during a meeting in Riyadh today.

Salah bin Jamal Khashoggi shared a stern handshake with Crown Prince Mohammed bin Salman, the powerful heir to Saudi Arabia's throne, at the city's Yamama Palace.

King Salman was also present as the royals 'offered their condolences' to grieving family members, who included Salah's brother Sahel. A friend of the Khashoggi family said the government banned them from leaving the country last year in a bid to pressure the journalist to return home.

As the de facto ruler of the kingdom, the Crown Prince has been widely blamed for the death, which was carried out by a hit squad of senior Saudi intelligence officials. Critics suspect he ordered the high-profile operation or at least knew about it.

It comes amid claims parts of the writer's body including his disfigured face have been found in the grounds of the Saudi consul general's home in Istanbul, with separate reports saying the remains were found down a well at the property.

This afternoon, Turkish police found three suitcases, a laptop and clothes possibly belonging to Khashoggi in a Saudi diplomatic car which was abandoned in an underground car park in the city, CNN Turk reported.

On Tuesday night US President Donald Trump criticised the Saudi operation to kill journalist Jamal Khashoggi. 'They had a very bad original concept. It was carried out poorly and the cover-up was one of the worst cover-ups in the history of cover-ups,' Trump declared in the Oval Office

The discovery came after the G7 nations issued a rare joint statement demanding a 'full and rigorous' investigation into the killing and punishment for those to blame.

It read: 'We reiterate our expectation for a thorough, credible, transparent, and prompt investigation by Saudi Arabia, in full collaboration with the Turkish authorities, and a full and rigorous accounting of the circumstances surrounding Mr Khashoggi's death.

'Those responsible for the killing must be held to account. Saudi Arabia must put in place measures to ensure something like this can never happen again. The circumstances of Mr Khashoggi's death reaffirm the need to protect journalists and freedom of expression around the world.'

On Tuesday night US President Donald Trump criticised the Saudi operation to kill Khashoggi. 'They had a very bad original concept. It was carried out poorly and the cover-up was one of the worst cover-ups in the history of cover-ups,' Trump declared in the Oval Office.

'It's very simple. Bad deal, should have never been thought of. Somebody really messed up,' Trump said. But he also said Saudi Arabia had been a 'great ally' and a top U.S. investor.

'They are doing hundreds of billions of dollars worth of investments and, you know, So many jobs,' he said. Then he pointed to regional rival Iran, saying they have been 'vicious, horrible.'

'And that's no excuse for what happened with Saudi Arabia. No excuse whatsoever. But you take a look, it's a rough part of the world. It's a nasty place. It's a nasty part of the world,' Trump said. Then he added: 'But, if what happened happened, and if the facts check out, then it's something that's very bad.'

Following the arrest of 18 suspects by Saudi Arabia, Trump said the person who 'thought of' the idea should be held accountable. 'Whoever thought of that idea, I think is in big trouble. And they should be in big trouble. Okay?' he said

Earlier, the Turkish leader Recep Tayyip Erdogan said Khashoggi's 'savage' murder was planned by a Saudi hit squad who disabled CCTV at the Istanbul consulate before killing the writer and giving his body to a local fixer.

Khashoggi's son was 'disengaged and vulnerable' while the Crown Prince was 'compassionate': Body language expert analyses the meeting Picture 1: We can see from Salah's face that his chin is a fraction high, the front lips are pushed slightly forward, with the corners pulled inwards and the eye muscles are still, suggesting an overall mix of being emotionally disengaged, a sense of vulnerability together with a held-in anger. These are all emotions that we might well feel under the circumstances of uncertainty around what has happened to his father. His arm is also muscularly disengaged. It is held with a formal extension without the usual elbow bend. His hand doesn't grip as in a usual handshake leaving the fingers open and disconnected. The Crown Prince appears to deliberately lower his head as if to show condolence and compassion. His handshake is open and gentle but again without the usual muscle involvement. Perhaps he is taking his cue from Salah here to create rapport? His body language is calm, open and respectful. Picture 2: The King, lowering himself to show respect to Salah, shows tight lip corners with the cheeks falling away to the sides. His eyebrows are raised which seems to give an overall feeling of compassion and bewilderment. His hand is firmer than the Crown Princes' was when he shook Salah's hand. In the background we see the Crown Prince once again lowering his head to show respect but he seems more relaxed when speaking here to Sahel than to Salah as we see a hint of smile and his handshake is more engaged. Picture 3: We see the King lowering himself and pointing his finger (I think) directly at Salah. The Crown Prince appears to have closed off here. He looks down with some tension in the lips and firmly crossed arms as if in deference to his father. As we don't know what is being said it's hard to read the pointing gesture. With his finger that firmly straight, it does seem to be saying, 'Of this be certain ...'. But what he is certain of, we cannot know.

Erdogan also assured the family of the slain journalist that Ankara would do 'everything' to solve the case as he offered his condolences over during a telephone call to Khashoggi's son Abdullah.

He said a three-person team arrived in Istanbul the day before Mr Khashoggi's murder and checked into a hotel before heading to the consulate.

Another team from the consulate carried out exploratory searches in the Belgrad forest and Yalova, a woodland area which Turkish police have searched. He also confirmed that the hard-disk in the camera system at the consulate was 'ripped out'.

According to a Sky News report, parts of the writer's body were discovered in the garden of the house, but it is not clear how much of his remains were found.

A separate report in Turkey claimed that the body parts were found in a well at the property. But in a speech earlier today, Turkish president Recep Tayyip Erdogan suggested a corpse had not yet been discovered and called on Saudi Arabia to reveal its location.

If proved true, questions will be raised over why it has taken so long to discover any of Khashoggi's remains.

Suitcases found in Saudi diplomatic car This afternoon, Turkish police found three suitcases, a laptop and clothes in a Saudi diplomatic car which was abandoned in an underground car park in the city, CNN Turk reported. It is not clear if the possessions belonged to Khashoggi - who did not have any suitcases or a laptop on him when he entered the Istanbul consulate before his murder. Turkish police are still looking for his body. According to a car park employee, a Saudi consulate attaché unloaded the suitcases from the car, put them in his vehicle and drove away. The employee said he asked the attaché jokingly: ‘Khashoggi’s body is not inside the suitcases, is it?’ He said the attaché laughed and answered ‘no’. It was claimed that Saudi Arabia had originally prevented a police search of the abandoned car because it had a diplomatic licence plate. Advertisement

UK Prime Minister Theresa May's official spokesman said: 'We are aware of the reports, they are deeply disturbing. Our thoughts are with the family of Jamal Khashoggi for whom they must be particularly distressing.

The location of Mr Khashoggi's body is just one of the questions we need answers to and as such we await the full results of the Turkish investigation.'

Saudi Arabia's consul general Mohammed al-Otaibi fled Istanbul last week before his home was searched by Turkish police. He was then placed under investigation and relieved of his position, the kingdom said in a statement. Earlier today, Erdogan said he had told King Salman that the consul was 'incompetent'.

In an explosive speech today, Erdogan said there were strong signs a Saudi team plotted to kill the dissident journalist days before his death on October 2.

The 64-year-old described it as a 'political murder' but stopped short of directly blaming Saudi Crown Prince Mohammed bin Salman - the effective ruler of the kingdom - instead demanding to know 'who gave the orders' for the operation.

In response, Saudi King Salman said at a cabinet meeting this afternoon that those responsible for Khashoggi's slaying would be held 'accountable'.

Officials including 'intelligence, security and forensic personnel' were seen entering the building where Khashoggi disappeared, Erdogan said, while some were seen exploring a nearby forest beforehand.

The revelation will fuel speculation the team was scouting an area where they could potentially ditch a body.

As the fallout from the killing continued today,

Turkish media reported that intelligence officers intercepted no fewer than seven phone calls from a member of the hit squad to the private office of the Saudi Crown Prince on the day Khashoggi went missing

Separate reports claimed Khashoggi's fingers were cut off and sent back to Saudi Arabia as 'proof' of a successful mission

Saudi and Turkish intelligence sources told Reuters a royal aide named Saud Al-Qahtani, who was sacked over the killing, directed the murder at the consulate by giving orders over Skype, telling the hit squad 'bring me the head of the dog'

A Future Investment Initiative conference, dubbed 'Davos in the Desert', opened in Riyadh with Energy Minister Khalid al-Falih saying 'these are difficult days' for Saudi Arabia and calling the country a nation 'in crisis'.

Despite global outrage over Khashoggi, Saudi Arabia is expected to sign deals worth more than $50 billion on the opening day alone

A friend of Khashoggi claims he was working on exposing Saudi Arabia's use of social media 'troll farms'

In his speech, Erdogan called for 18 people arrested in Saudi Arabia to be tried in Istanbul, but said blaming some intelligence members for the killing will not satisfy Turkey 'or the international community'.

Speaking to members of his AK Party in parliament, he also questioned why a corpse had yet to be found and called on Saudi Arabia to reveal the identity of a 'local cooperator' who purportedly took the body.

The majority of his claims have already been leaked, but for Erdogan to make the revelations in a speech to parliament raises the stakes in the region.

Erdogan's speech was previously pitched as revealing the 'naked truth' about Khashoggi's slaying. Instead it served merely to put a named source to information already circulated by anonymous officials.

Khashoggi flew to his death from London Jamal Khashoggi flew in to Istanbul from London just hours before his ‘savage’ murder, the president of Turkey has revealed. Recep Tayyip Erdogan said Mr Khashoggi had returned to Turkey on October 2 – the day of his death. He added that the journalist had been called at 11.50am that morning to confirm his appointment at the Saudi consulate. At 1.08pm, Mr Khashoggi walked into the consulate building. Footage has emerged of Mr Khashoggi speaking at a conference on Israeli- Palestinian relations in London three days before his death. Speaking at the Wellcome Collection on September 29, he said diplomatic solutions to resolve the Palestine conflict had failed. He said the issue of Palestinian self-determination was a ‘burning topic’ in Saudi Arabia, but it was for Palestine to decide on its future without outside interference. Advertisement

One senior western diplomat in Turkey told Bloomberg the crisis was a 'gift from God' for Erdogan as he tries to capitalise on it to spark a change in the balance of power in Saudi Arabia and increase his own influence across the Middle East.

Just hours earlier, a major Saudi investment forum opened under the heavy shadow of the murder after key delegates pulled out.

The murder of the Washington Post contributor has damaged the international reputation of Saudi Crown Prince Mohammed bin Salman who has spearheaded a reform drive in the kingdom.

Erdogan said three operatives arrived in Istanbul the day before Khashoggi's killing on an apparent reconnaissance mission. The next day 15 people came to the consulate.

'Why did these 15 people meet in Istanbul on the day of the murder? We are seeking answers to this. Who are these people receiving orders from?' Erdogan said.

'My demand is that 18 people be tried in Istanbul,' Erdogan said in his speech, referring to 18 people including security officials who have already been detained by Riyadh.

He added that 'all those who played a role in the murder' had to face punishment.

Erdogan said that the murder was 'planned' days in advance according to a 'roadmap' set up by a Saudi team who were sent to Istanbul for the purpose.

The surveillance system at the Saudi consulate in Istanbul was deactivated on purpose, he said.

The murder of Jamal Khashoggi: Key moments surrounding the writer's disappearance and death Saudi journalist Jamal Khashoggi, who wrote critically of the kingdom's policies and Saudi Crown Prince Mohammed bin Salman, was killed in the Saudi Consulate in Istanbul earlier this month. Turkish officials say a 15-men team tortured, killed and dismembered the writer, while Saudi Arabia says he died in a 'fistfight.' Here are some key moments in the slaying of the Washington Post columnist: BEFORE HIS DISAPPEARANCE September 2017: The Post publishes the first column by Khashoggi in its newspaper, in which the former royal court insider and longtime journalist writes about going into a self-imposed exile in the U.S. over the rise of Prince Mohammed. His following columns criticize the prince and the kingdom's direction. September 28, 2018: Over a year after the Post published his first column, Khashoggi visits the Saudi Consulate in Istanbul, seeking documents in order to get married. He's later told to return October 2, his fiancee Hatice Cengiz says. Turkish President Recep Tayyip Erdogan says a plan or a 'road map' to kill Khashoggi was devised in Saudi Arabia during this time. September 29: Khashoggi travels to London and speaks at a conference. October 1: Khashoggi returns to Istanbul. At around 4.30pm, a three-person Saudi team arrives in Istanbul on a scheduled flight, checks in to their hotels then visits the consulate, according to Erdogan. The Turkish president says another group of officials from the consulate travel to a forest in Istanbul's outskirts and to the nearby city of Yalova on a 'reconnaissance' trip. Jamal Khashoggi (right) arriving at the Saudi Arabian consulate in Istanbul on October 2. He has not been seen since and Turkey has accused Saudi agents of murdering him THE DAY OF HIS DISAPPEARANCE 3.28am, October 2: A private jet arrives at Istanbul's Ataturk Airport carrying some members of what Turkish media will refer to as a 15-member Saudi 'assassination squad.' Other members of the team arrive by two commercial flights in the afternoon. Erdogan says the team includes Saudi security and intelligence officials and a forensics expert. They meet at the Saudi Consulate. One of the first things they do is to dismantle a hard disk connected to the consulate's camera system, the president says. 11.50am: Khashoggi is called to confirm his appointment at the consulate later that day, Erdogan says. 1.14pm: Surveillance footage later leaked to Turkish media shows Khashoggi walking into the main entrance of the Saudi Consulate. No footage made public ever shows him leaving. His fiancee waits outside, pacing for hours. 3.07pm: Surveillance footage shows vehicles with diplomatic license plates leaving the Saudi Consulate for the consul general's home some 2 kilometers (1.2 miles) away. 5.50pm: Khashoggi's fiancee alerts authorities, saying he may have been forcibly detained inside the consulate or that something bad may have happened to him, according to Erdogan. 7pm: A private plane from Saudi Arabia carries six members of the alleged Saudi squad from Istanbul to Cairo, the next day returning to Riyadh. 11pm: Seven members of the alleged Saudi squad leave on another private jet to Dubai, United Arab Emirates, which the next day returns to Riyadh. Two others leave by commercial flights. Erdogan confirms reports that a 'body double' - a man wearing Khashoggi's clothes, glasses and a beard - leaves the consulate building for Riyadh with another person on a scheduled flight later that day. CCTV images showed a a private jet alleged to have been used by a group of Saudi men suspected of being involved in Saudi journalist Jamal Khashoggi's death INITIAL REACTION October 3: Khashoggi's fiancee and the Post go public with his disappearance. Saudi Arabia says Khashoggi visited the consulate and exited shortly thereafter. Turkish officials suggest Khashoggi might still be in the consulate. Prince Mohammed tells Bloomberg: 'We have nothing to hide.' October 4: Saudi Arabia says on its state-run news agency that the consulate is carrying out 'follow-up procedures and coordination with the Turkish local authorities to uncover the circumstances of the disappearance of Jamal Khashoggi after he left the consulate building.' October 5: The Post prints a blank column in its newspaper in solidarity with Khashoggi, headlined: 'A missing voice.' October 6: The Post, citing anonymous Turkish officials, reports Khashoggi may have been killed in the consulate in a 'preplanned murder' by a Saudi team. October 7: A friend of Khashoggi tells the AP that officials told him the writer was killed at the consulate. The consulate rejects what it calls 'baseless allegations.' October 8: Saudi Arabia's ambassador to Turkey is summoned over Khashoggi's disappearance and alleged killing. LEAKED FOOTAGE October 9: Turkey says it will search the Saudi Consulate as a picture of Khashoggi walking into the diplomatic post surfaces. October 10: Surveillance footage is leaked of Khashoggi and the alleged Saudi squad that killed him. Khashoggi's fiancee asks President Donald Trump and first lady Melania Trump for help. October 11: Turkish media describes Saudi squad as including royal guards, intelligence officers, soldiers and an autopsy expert. Trump calls Khashoggi's disappearance a 'bad situation' and promises to get to the bottom of it. October 12: Trump again pledges to find out what happened to Khashoggi. October 13: A pro-government newspaper reports that Turkish officials have an audio recording of Khashoggi's alleged killing from his Apple Watch, but details in the report come into question. INTERNATIONAL UPROAR October 14: Trump says that 'we're going to get to the bottom of it, and there will be severe punishment' if Saudi Arabia is involved. The kingdom responds with a blistering attack against those who threaten it, as the manager of a Saudi-owned satellite news channel suggests the country could retaliate through its oil exports. The Saudi stock exchange plunges as much as 7 percent at one point. October 15: A Turkish forensics team enters and searches the Saudi Consulate, an extraordinary development as such diplomatic posts are considered sovereign soil. Trump suggests after a call with Saudi King Salman that 'rogue killers' could be responsible for Khashoggi's alleged slaying. Trump says Secretary of State Mike Pompeo will travel to the Mideast over the case. Meanwhile, business leaders say they won't attend an economic summit in the kingdom that's the brainchild of Prince Mohammed. October 16: A high-level Turkish official tells the AP that 'certain evidence' was found in the Saudi Consulate proving Khashoggi was killed there. Pompeo arrives for meetings in Saudi Arabia with King Salman and Prince Mohammed. Meanwhile, Trump compares the case to the appointment of now-Supreme Court Justice Brett Kavanaugh during his confirmation hearing, saying: 'Here we go again with you're guilty until proven innocent.' October 17: Pompeo meets with Turkey's president and foreign minister in the Turkish capital, Ankara. Turkish police search the official residence of Saudi Arabia's consul general in Istanbul and conduct a second sweep of the consulate. October 18: A leaked surveillance photograph shows a member of Prince Mohammed's entourage walked into the consulate just before Khashoggi vanished there. October 20: Saudi Arabia for the first time acknowledges Khashoggi was killed in the consulate, claiming he was slain in a 'fistfight.' The claim draws immediate skepticism from the kingdom's Western allies, particularly in the U.S. Congress. October 22: A report says a member of Prince Mohammed's entourage made four calls to the royal's office around the time Khashoggi was killed. Police search a vehicle belonging to the Saudi consulate parked at an underground garage in Istanbul. October 23: Erdogan says Saudi officials murdered Khashoggi after plotting his death for days, demanding that Saudi Arabia reveal the identities of all involved. Advertisement

'First they (the Saudis implicated) removed the hard disc from the camera system,' Erdogan said. 'This is a political murder,' he added.

But Erdogan added he still wanted answers on numerous issues including 'who gave orders' to the team and where the corpse is.

Erdogan did not mention Prince Mohammed by name in the speech but said he was confident of the full cooperation of his father Saudi King Salman in the probe.

'To blame such an incident on a handful of security and intelligence members would not satisfy us or the international community,' Erdogan said.

'Saudi Arabia has taken an important step by admitting the murder. As of now we expect of them to openly bring to light those responsible - from the highest ranked to the lowest - and to bring them to justice,' the Turkish president said.

'All evidence gathered shows that Jamal Khashoggi was the victim of a savage murder. To cover up such a savagery would hurt the human conscience,' he said.

He said no Saudi linked to the murder should enjoy diplomatic immunity as set out by the Vienna Convention.

'The Vienna Convention and other international regulations don't allow for a savage murder to be protected from investigation by diplomatic immunity.'

This morning, one of Erdogan's left-wing rivals, Patriotic Party leader Dogu Perincek, said that some of Khashoggi's remains had been recovered.

Perincek told Turkish TV that parts of the body of the murdered Saudi journalist have been found in a well in the grounds of the Saudi consul general's home. However, he did not expand on the claims, and authorities have not commented on his statement, news website Haberler reported.

This morning, Saudi Arabia's foreign minister said the investigation into the killing will produce the truth about what happened. Adel al-Jubeir also pledged that mechanisms will be put in place so that 'something like this can never happen again'

Erdogan today said a Saudi team entered the consulate the day of the killing, and that three men from the team went on an exploration trip to Belgrad forest in Istanbul and Yalova, a 55 mile drive south of Istanbul.

Turkish news website Haberturk now reports one of the vehicles used by the hit squad had been driven to and from Yalova district several times and that there is a possibility one of the members of the 'hit squad' has a summer house there.

The website pictured a three-floor red building which they claim to be the summer house in question, which has been raided by police.

Turkish officials believe the Saudis may have dumped his remains in Belgrad Forest and at a rural location near Yalova.

After initially denying any knowledge of Khashoggi's fate, the kingdom gave a new story on Saturday, saying he died in a 'fistfight.'

Saudi Arabia said 18 Saudis were arrested and that several top intelligence officials were fired over the killing, but critics alleged that the punishment was designed to absolve the Crown Prince Mohammed bin Salman, the kingdom's heir-apparent, of any responsibility.

Erdogan earlier promised the case 'will be revealed in all its nakedness' in a speech to ruling party members.

Turkey's foreign minister, meanwhile, said his country would cooperate with international bodies if they were to launch an independent probe into the Khashoggi's killing.

'Hitman made SEVEN calls to the Saudi Crown Prince's private office' on the day Khashoggi was killed Turkish intelligence officers intercepted more than a dozen phone calls by the man described as the 'spinal cord' of the Saudi hit squad accused of murdering Jamal Khashoggi. Major General Maher Abdulaziz Mutrib, a former diplomat who was once posted to Britain, has also been pictured travelling alongside the Crown Prince on official visits to the UK and the US. Seven of the phone calls he made on the day Khashoggi was killed were made directly to the Saudi Crown Prince's private office. According to Turkish newspaper Yeni Safak, Mutrib spoke to Badr al-Asaker, head of the Crown Prince's private office, four times after Khashoggi was killed. Major General Maher Abdulaziz Mutrib, pictured outside Downing Street in March during the Crown Prince's state visit, was described as the 'spinal cord' of a Saudi death squad Left, on the way in: Mustafa al-Madani enters the consulate in a checked shirt.

Right - Job done: The Saudi then changed back into his own clothes Last night, one Saudi and one Turkish intelligence source told Reuters that a Saudi royal aide sacked over the killing directed the murder by giving orders over Skype. Saud Al-Qahtani, who ran social media for the crown prince, allegedly insulted the journalist after he was seized in the consulate before telling a hit squad 'bring me the head of the dog'. He was sacked from his post on Saturday and was made chairman of the Saudi Federation for Cybersecurity, Programming and Drones, a role he had held before. It has since also been claimed that that members of the hit squad sent Mr Khashoggi's fingers back to Riyadh to prove the mission's success. Advertisement

In an interview with state-run Anadolu Agency, Mevlut Cavusoglu also said Turkey has not shared evidence concerning his death at the Saudi consulate with any country but added that there may have been 'an exchange of views between intelligence organisations.'

U.S. President Donald Trump said on Monday that he is not satisfied with the explanations he's heard about the killing of Khashoggi and is awaiting reports from U.S. personnel returning from the region.

'We're going to get to the bottom of it. We have people over in Saudi Arabia now. We have top intelligence people in Turkey. They're coming back either tonight or tomorrow,' Trump told reporters at the White House before leaving for a political rally in Texas.

A high-profile economic forum in Saudi Arabia began Tuesday in Riyadh, the kingdom's first major event on the world stage since Khashoggi's killing.

The Future Investment Initiative forum, the brainchild of Prince Mohammed, is aimed at drawing more foreign investment into the kingdom and helping create desperately needed jobs for its youthful population.

Prince Mohammed was not at the forum when it started.

On Monday, leaked surveillance video showed a man strolling out of the diplomatic post hours after Khashoggi disappeared into the consulate, apparently wearing the columnist's clothes as part of a macabre deception to sow confusion over his fate.

The new video broadcast by CNN, as well as a pro-government Turkish newspaper's report that a member of Prince Mohammed's entourage made four calls to the royal's office from the consulate around the same time, put more pressure on the kingdom.

Saudi Arabia is in crisis after Khashoggi murder, energy minister tells 'Davos in Desert' conference Saudi Arabia is a nation 'in crisis', the country's energy minister told an international investment conference on Tuesday, following global outrage over the murder of Jamal Khashoggi. Saudi Energy Minister Khalid al-Falih told the Future Investment Initiative, which opened in Riyadh today, that 'these are difficult days' for Saudi Arabia, calling Khashoggi's killing 'abhorrent'. However, despite his comments - and a wave of cancellations from high-ranking Western political figures and business titans - Saudi Arabia said it is expected to sign deals worth more than $50 billion on the opening day of the conference alone. Saudi employees print badges of participants of the Future Investment Initiative conference, which kicks off Tuesday, in Riyadh The Future Investment Initiative forum is the brainchild of Crown Prince Mohammed bin Salman, aimed at drawing more foreign investment into the kingdom and to help create desperately needed jobs for its youthful population. But the summit, dubbed 'Davos in the desert' has been overshadowed by growing global outrage over the murder of Khashoggi inside the kingdom's consulate in Istanbul earlier this month. Dozens of executives - from bankers JP Morgan to carmaker Ford and ride-hailing app Uber - scrapped plans to attend, prompting organisers to take down a list of speakers from its website. Saudi Crown Prince, Mohammed bin Salman, right, talks with the U.S. Secretary of the Treasury Steven Mnuchin in Riyadh, Saudi Arabia ahead of the conference In further embarrassment to the regime, the summit's website was infiltrated by hackers accusing the regime of financing terrorism on Monday. Hackers edited the event's poster to show the kingdom's powerful crown prince as an ISIS executioner wielding a bloody sword with Khashoggi kneeling before him. The hackers wrote underneath the image: 'For the sake of security of children worldwide, we urge all countries to put sanction [sic] on the Saudi regime.' 'The regime, aligned with the United States, must be kept responsible for its barbaric and inhuman action, such as killing its own citizen Jamal Khashoggi and thousands of innocent people in Yemen. 'The medieval Saudi regime is one of the sources for #Terrorism_Financing in the world.' The website for Saudi Arabia's 'Davos in the desert' summit was hacked on Monday to show Crown Prince Mohammed bin Salman appearing to behead Jamal Khashoggi. The hackers also published what they purport is a list of 'a thousand terrorists and spies of the Saudi Arabia regime who perform malicious activities around the world' - complete with their phone numbers and email addresses. The summit's website has since been taken down. The forum last year proved to be a glitzy affair that drew more international business attention to the kingdom, however despite the luxurious setting at the five-star Ritz-Carlton hotel, this year's event will forever be linked to the brutal murder of Khashoggi.

Meanwhile, Turkish crime-scene investigators swarmed a garage Monday night in Istanbul where a Saudi consular vehicle had been parked.

Saudi Arabia's foreign minister, meanwhile, said Tuesday the investigation into the killing of Khashoggi would produce the truth about what happened and that his country was committed to ensuring 'that the investigation is thorough and complete and that the truth is revealed and that those responsible will be held to account.'

Foreign Minister Adel al-Jubeir, in Indonesia, also pledged that mechanisms will be put in place so that 'something like this can never happen again.'

The murder of the Washington Post contributor has damaged the international reputation of Saudi Crown Prince Mohammed bin Salman who has spearheaded a reform drive in the kingdom.

He who was credited with key changes including giving women the right to drive but is now accused of having ordered Khashoggi's murder - a claim Riyadh denies.

Reports in pro-government Turkish media have suggested he was slowly strangled in an operation by a 15 person assassination team. But these claims have yet to be confirmed on the record and Khashoggi's remains have also not been found.

German Chancellor Angela Merkel said Berlin would not export arms to Riyadh 'in the current situation,' despite Germany's approval last month of 416 million euros' ($480 million) worth of arms exports in 2018.

Despite also pulling out of the Davos-style summit, US Treasury Secretary Steven Mnuchin met the crown prince behind closed doors for bilateral talks in Riyadh today. CIA Director Gina Haspel, meanwhile, headed for Turkey, although details of her trip were not immediately clear.

Khashoggi was 'working to expose Saudi Arabia's use of social media trolls and had been harassed on Twitter' before he was killed, his friend claims Jamal Khashoggi was working to expose Saudi Arabia's use of social media trolls before he was murdered, one of his friends has revealed. Omar Abdelaziz, who now lives in Canada, told Euronews he and Khashoggi had been working on a series of projects together, including an exposé of the use of social media by pro-government accounts. He told the website, that his friend had been targetted on Twitter by so-called 'electronic flies' as they worked together on human rights campaigns. Jamal Khashoggi (pictured) was working to expose Saudi Arabia's use of social media trolls before he was murdered, one of his friends has revealed He said: 'I have known (Khashoggi) for three years but I did not agree with him politically because he seemed closer to the official approach. 'But things changed since Khashoggi left Saudi Arabia in September 2017. We reviewed this relationship and we got in touch almost every day.' On Saturday, the New York Times reported that Saudi Arabia deployed an online army to harass Khashoggi and other critics of the kingdom on Twitter. The efforts to attack Khashoggi and other influential Saudis, and sway public opinion against them on the social media service, included a so-called troll farm based in Riyadh and a suspected spy within Twitter that the kingdom utilised to monitor user accounts, the New York Times reported. Twitter declined to comment. A representative from the Saudi embassy in Washington did not immediately respond to a request for comment. Advertisement

White House advisor and Trump's son-in-law Jared Kushner, believed to have close ties with the crown prince, said he had urged him to be 'fully transparent', stressing that 'the world is watching'.

Speaking in Jakarta, Saudi Arabia's Foreign Minister Adel al-Jubeir vowed 'a thorough and complete investigation'. He said procedures would be put in place to 'ensure that something like this can never happen again.'

Omer Celik, spokesman of Erdogan's ruling party, said the killing 'was planned in an extremely savage manner,' and that 'there has been a lot of effort to whitewash this'.

Some of the consulate employees who gave testimony to Turkish prosecutors said they had not been given holiday on the day that Khashoggi was murdered, despite reports in local media, and they finished work at 3.30pm.

The employees were also quoted as saying that they did not 'see or hear' any sounds related to a fight despite Riyadh's claims that Khashoggi died during a 'brawl'.

Erdogan has so far stopped short of directly pointing the finger at Riyadh. Analysts say he preferred to authorise the leak of incriminating information to pro-government media to put pressure on the kingdom.

He has twice held telephone talks with King Salman on the crisis, interpreted by some as a bid to sideline the ageing Saudi monarch's son Prince Mohammed.
