The third terrorist behind Saturday's London Bridge terror attack has been named as Youssef Zaghba

British authorities were warned about one of the men behind the London Bridge attack - a 22-year-old Italian-Moroccan - who declared 'I am going to be a terrorist' as he tried to travel to Syria from Italy.

It has also emerged that Youssef Zaghba, who was born in Fez, called his Italian mother in Bologna to say goodbye two days before ramming a van into innocent civilians in the capital.

His mother, Valeria told Italian newspaper L'Espresso that he called early on Thursday afternoon.

She said: 'Thinking back to then, I realize that in his mind that was his farewell. He didn’t say anything special, I could feel it in his voice.'

'When children make mistakes, parents always feel guilty. I did my best and I think he was crossed by doubts inside. We have always checked his friendships and ensured he did not trust the wrong people. But he had the Internet and everything comes from there.'

An emotional Valeria also condemned her son's actions and reached out to the relatives of his victims.

She added: 'A mother can understand the pain of another mother. I know that nothing can be done but I’m ready to do everything that can bring peace.

'I realize that asking for forgiveness doesn’t mean anything, that’s why I commit myself and I promise to dedicate my life not to allow this to happen anymore.'

Alarmingly, Zaghba was caught on his way to the war-torn country last year, according to Italian media.

The other two attackers were named yesterday as Pakistani-born Khuram Butt (left), who had appeared on a TV show called 'The Jihadi Next Door', and Moroccan-born Rachid Redouane (right)

Zaghba's mother Valeria had returned to this house in the countryside near Bologna after her marriage to his father, Mohammed, fell apart. He visited her on several occasions before moving to London, according to Italian media

He was stopped at Bologna airport last year with a one-way ticket to Istanbul, carrying just a backpack, a passport and a mobile phone with ISIS propaganda films on it.

He told authorities: 'I am going to be a terrorist.'

Officials in Italy say they tipped off British authorities about Zaghba but he was apparently able to enter Britain and get a job in a London restaurant.

An Italian intelligence source said that Zaghba had since been acquitted of terrorism charges but was on a 'persons at risk' list - similar to a UK 'watch list', according to Corriere Della Sera.

Italy's counter-terrorism base in Rome immediatley contacted MI5, according to a source, but UK authorities have not found any dossiers regarding Zaghba or seen his name on any 'watch lists'.

Reports in Italy suggest the 22-year-old had since got a 'seasonal job' in a London restaurant and continued to speak to his mother back home.

His aunt, 85-year-old Franca Lambertini, who lives in a house adjacent to Valeria, told that she saw her nephew 'a very good boy' -until now

According to the terrorist's relative, he came back to Italy four or five months ago and seemed 'normal'

His aunt, Franca Lambertini, who lives in a house adjacent to Valeria, said: 'He was a very good boy, but now I can't say that anymore.

'I saw him few months ago, four or five, and he seemed normal. He went to London to find a job with a father's relatives, or at least this was what he said.

'She [Valeria] came back from Morocco two years ago, she wasn't happy anymore but she didn't tell me why.

'She used to wear a niqab, but now she only wears a veil. I always asked her "why?" but she said she liked it and she felt comfortable with it".

The Met Police have insisted Zaghba was not a 'subject of interest', but the claims in Italy will raise further questions of security services over why the three attackers weren't under closer surveillance.

It is thought Italian officials uploaded his name onto a Europe wide database rather than contact British authorities directly.

A LinkedIn page under his name shows that appeared to show him working for Marriott Hotel at Regent's Park, but the chain has denied having any record of him.

A spokesman said: 'Following your enquiry earlier today to the Marriott Regents Park regarding Mr. Zaghba, we have thoroughly checked our records and we do not have any record of Mr. Zaghba being an employee at the hotel.

'We have also spoken to all of our agency partners who supply temporary workers and they also have no record of Mr. Zaghba being on their books.'

Reporters approached his mother's home today but she has not been seen 'for some time', the town's mayor said

In a further embarrassment for British authorities, Zaghba's identity was revealed in Italy before Scotland Yard confirmed it, similar to how details of the Manchester bombing were leaked in the US before they were released by police in the UK.

Scotland Yard described Zaghba as 'of east London', suggesting he has been in the capital for some time.

Reports in Italy say he was born in Morocco at a time when his parents lived in north Africa. It is understood his mother had converted to Islam at the time.

His parents are now said to have separated and his mother has moved back to the Bologna area, where Zaghba frequently visited her from Morocco. His father, Mohammed, is believed to remain in north Africa.

His mother had concerns over her son's behaviour after he was picked up at the airport and reported him to police, who monitored him when he later visited, according to La Repubblica.

She lived in a small village in the hills of the Emilia-Romagna region, which is famed for Parma ham, Parmesan cheese and Sangiovese wine, but was her home appeared empty when visited by reporters today.

The mayor of her town, Daniele Ruscigno, told reporters: 'He [Zaghba] never lived here, the only member of the family that lived here was the mother, who was known but has not been seen around for some time.'

Naming the third attacker today, a Scotland Yard spokesman said: 'While formal identification is yet to take place, detectives believe he is 22-year-old Youssef Zaghba, from east London. The deceased's family have been informed.

'He is believed to be an Italian national of Moroccan dissent. He was not a police or MI5 subject of interest.'

The attackers were seen walking through Borough Market during their murderous rampage

The two other attackers - Khuram Shazad Butt and Rachid Redouane - were named yesterday.

Butt, 27, was probed two years before his murderous rampage but officials downgraded the investigation because they did not suspect the married father of two was planning an attack.

Morocco's links to ISIS More than 1,500 Moroccans have joined ISIS since the terror group declared a so-called 'caliphate' in Syria and Iraq. Morocco's government has said young men in the country are being targeted and radicalised on social media and encouraged to take up arms. Figures from the country suggest of those who have made the journey to Syria, around 300 are women, and a similar number are teenagers. Last year, authorities announced they had thwarted a 'dangerous' ISIS-led plot to murder Western tourists and diplomats in the country. Advertisement

Incredibly, Butt even secured a job working on the Tube last year and had access to tunnels under the Houses of Parliament while working at Westminster station.

Pakistani-born Briton Butt, who came to the UK as an asylum seeker, was able to mastermind the murder of seven and maiming of 48 others in plain sight on Saturday night.

There are growing calls for Scotland Yard and MI5 to explain why they failed to act on the repeated warnings about Butt's extremism.

Police said Redouane, 30, 'claimed' to be Moroccan-Libyan. He was also carrying an Irish identity card when he was shot dead by police during Saturday's rampage, that left seven dead.

But there were a number of unanswered questions about Radouane's background, with police admitting they are not completely sure about his true identity.

Scotland Yard said he was also known as Rachid El-khdar, and used a different date of birth which made him five years younger.

Redouane's British wife Charisse O'Leary, 38, was among seven women detained by police in the aftermath of the attacks. A total of ten people remained in custody last night.

Mayor of London Sadiq Khan said today both must reveal what they knew about him and his predecessor Boris Johnson said people were right to question how he had 'slipped through our net' while in plain sight.

Foreign Secretary Boris Johnson, who served as Mayor of London, said people were right to question how Butt had 'slipped through our net' while in plain sight.

Mr Johnson said: 'People are understandably right to look at photographs in today's papers of the TV show that this guy was in and to ask what happened, how did this person slip through our net in the way that he seems to have done?'

Theresa May has said she expects police and security services to launch a review after three terrorists slipped through the net to launch the devastating attack at London Bridge.

Mrs May told Sky News: 'MI5 and the police have already said they would be reviewing how they dealt with Manchester and I would expect them to do exactly the same in relation to London Bridge.

'What Government needs to do is, and what the Government that comes in after Thursday's election needs to be willing to do, is to give more powers to the police and security service when they need them, needs to deal with this issue of terrorism and extremism online and also needs to be able to call out extremism here in the United Kingdom.'

Celebrating Lee Rigby's death, ISIS flag on TV and the 7/7 link: The red flags that should have warned police Police and secret services considered Khuram Butt 'low priority' despite: Butt publicly abused moderate Muslims including 'traitors' who spoke out against the murder of Lee Rigby in 2013;

In 2015 he prepared to abandon his pregnant wife Zahrah to wage holy war in Syria, until relatives talked him out of it;

In the same year friends twice called the anti-terror hotline over his extremist behaviour and obsession with YouTube rants by hate preachers Another whistleblower warned he was trying to radicalise children in his local park

In 2016 appeared on the Channel 4 film The Jihadis Next Door and was filmed unfurling an ISIS-type flag in Regent's Park before rowing with police called by frightened members of the public;

Four months later - in May 2016 - he secured a job on the Tube and had access to tunnels under Parliament

He also had links to a key contact of Mohammed Siddique Khan - one of the 7/7 suicide bombers, who killed 52 people in London 12 years ago. Advertisement

Three terror attacks in three months ... and ALL killers were known to police: Fears over MI5 warning system as more slip through security net

The three terror attacks to hit Britain in the past three months - claiming 34 lives - have all been carried out by jihadis who were known to the police and MI5.

It raises questions about the security services' ability to watch the estimated 23,000 people in Britain considered a potential terror threat.

Last night it was confirmed that London Bridge massacre mastermind Khuram Butt, 27, had been investigated two years ago but was considered a lower risk threat.

Last month MI5 has launched urgent probes into why it missed the danger posed by the Manchester bomber Salman Abedi, 22.

Butt was known to both the police and MI5 who are awaiting what they described as international confirmation before naming the third terrorist

It came amid claims that the authorities were repeatedly told that Mr Abedi was a danger to the public.

Teachers and religious figures in Manchester who knew the killer raised concerns about his extremist views on numerous occasions over several years.

Home Secretary Amber Rudd said missed chances to catch Mr Abedi would be investigated, as it was claimed that US officials warned MI5 last year that he was planning an attack.

She said: 'Of course people will want to look afterwards to see whether there are signals that could have been learnt, how could we do this be‎tter.'

MI5 carried out a quick review of intelligence held abou‎t him in the aftermath of the May 22 attack.

The second inquiry will be more detailed and will look at the decision-making before the bombing, including what was known about his co-conspirators.

Last month MI5 has launched urgent probes into why it missed the danger posed by the Manchester bomber Salman Abedi, 22, left. The security services also admitted knowing of Khalid Masood, 52, right, before he killed five in Westminster in March

The British-born jihadi who killed four and injured 29 in Westminster in March was revealed to be a middle-aged criminal career who MI5 had investigated in the past and had a previous conviction for stabbing a man in the nose.

English teacher Khalid Masood, 52, a 'lone wolf' attacker, who was living in the Birmingham area, had a series of convictions for assault and other crimes.

Scotland Yard revealed how Masood was known by a number of aliases and MailOnline revealed he was born Adrian Elms to a single mother in Kent before his religious conversion.

Masood has used the names Khalid Choudry and Adrian Ajao among others.

He grew up in a £300,000 house in the seaside town of Rye, East Sussex and had a long criminal history.

His first conviction was for criminal damage in November 1983, when he was just 19. His last was for an attack in 2003, where he stabbed a 22-year-old man in the face, leaving him slumped in the driveway of a nursing home in Eastbourne. The victim was left needing cosmetic surgery after the vicious attack.

Michael Adebolajo, who murdered Lee Rigby, was not considered a serious threat by MI5 and they allegedly tried to recruit him

Masood is understood to have spent time in Lewes jail in East Sussex, Wayland prison in Norfolk and Ford open prison in West Sussex.

Masood had never been convicted of terror offences, although Theresa May revealed that he had been on MI5's radar a number of years ago.

Police insist there was no intelligence suggesting he was about to unleash a terror attack and described him as a peripheral figure.

British spies also failed to track the jihadi killers of soldier Lee Rigby – after MI5 decided they did not pose enough of a danger, an official report into the terror attack revealed three years ago.

Fusilier Rigby, 25, was run over and then butchered by Muslim converts Michael Adebolajo and Michael Adebowale in 2013 outside Woolwich barracks in south-east London.

Both men were known to MI5 – especially Adebolajo, 29, who was arrested in Kenya in 2010 attempting to cross the border into Somalia to fight for the African terror group Al Shabaab. He was passed to British spies.

In the months leading up the brutal murder in May 2013, the killer was also posting extremist material on the internet.

Despite their history of extremism MI5 assessed the pair as not posing a sufficient danger to require full monitoring.

Adebolajo has claimed spies attempted to turn him into an informant after he was arrested in Kenya in 2010 as he attempted to join extremists in Somalia.

After Drummer Rigby's murder, several witnesses said Adebolajo had complained of his treatment by the security services.

Adebolajo and Adebowale, both converts to Islam, had been known to the security services for up to eight years before the attack.

The spate of recent terror attacks in the UK has prompted the most intense scrutiny of the security services' efforts to keep potentially violent extremists in check since the aftermath of the July 7 bombings.

There are 500 current terrorism investigations, involving 3,000 'subjects of interest'. But in addition there are a further 20,000 people considered in the past whose risk remains 'subject to review'.

Scotland Yard said a small number of the highest priority investigations involve 'current attack planning' and these investigations 'command a significant proportion of our resource'.

Armed police on patrol. The three attacks have raised questions over whether Britain has the resources to combat terror

The remaining inquiries 'focus on other activities relating to active support or facilitation of terrorism'.

Authorities have stopped 18 plots since 2013, including five since the Westminster attack.

Shashank Joshi, senior research fellow at security think tank the Royal United Services Institute, said the latest case 'exemplifies the problems faced by the British authorities'.

He said: 'Khuram Butt was known to MI5, but it is important to remember that there are several thousand Britons regarded as capable of terrorism, and several hundred under active investigation.

'No intelligence agency in a democratic state can have the resources or powers to monitor such a large number of suspects indefinitely. Those who show no signs of active plotting will have to be downgraded.

'Where plots are low-tech, involving only widely available knives or vehicles, it will be harder to spot indications of plotting.'
