A teenage asylum-seeker who built a 'Mother of Satan' nail bomb in the bedroom of his foster home before trying to blow up a tube train is facing a lengthy jail term after he was convicted of attempted murder today.

Ahmed Hassan, 18, tried to kill 93 people by setting off a 'bucket bomb' at Parsons Green station in west London last September. Luckily the device failed to properly detonate, but still left 51 passengers with serious burns.

Hassan had left his native Iraq and travelled through Turkey, Italy and France before getting into the UK on the back of the lorry coming through the Channel Tunnel.

After being looked after in a charity-run shelter, he was taken in by loving foster parents Penelope and Ronald Jones in Sunbury-on-Thames, Surrey and sent to a local college.

But while his foster parents were away on holiday last summer, he studied YouTube videos on how to make explosives before building a bomb from household objects including Tupperware boxes, a vase and 2.2kg of knives, screwdrivers and nails.

Following today's verdicts, it can be reported:

Hassan had lived in ISIS-held territory before illegally entering Britain through the Channel Tunnel. He told immigration officers he had trained with the terror group.

But he was given a foster home and an education, although teachers started having fears over his radical views after he said he had a 'duty to hate Britain'.

A local council today admitted that its anti-extremism programme was not good enough.

Hassan researched bomb recipes on YouTube and bought components on Amazon.

The foster parents who took him were previously given honours by the Queen, but have reportedly told friends they want to stop fostering after the incident.

Many passengers were badly burned, but it was only a 'matter of luck' that scores were not killed, prosecutors have said.

The disturbing case will raise questions of authorities after it emerged Hassan told immigration officials he had been 'trained to kill' by ISIS, and said to a teacher it was his 'duty to hate Britain'.

Barnardo's worker Youseff Habibi told jurors he caught Hassan listening to an Arabic song on YouTube along the lines of 'coming to the slaughter in your own home' when he was living in a children's home in Surrey.

He later claimed he had made up the story about having been in an ISIS training camp in a bid to get asylum in Britain, but a jury rejected his claims that the bomb plot was a 'fantasy'.

The Old Bailey has heard Hassan built his fearsome bomb in his bedroom during the school holidays and used an Amazon gift token he won for being Student of the Year at Brooklands Sixth Form College in Weybridge, Surrey.

Video footage showed him carrying out experiments with a mobile phone in a back garden.

On September 15 last year, Hassan took his homemade device, wrapped in a Lidl cool bag, from his home in Sunbury to Wimbledon before leaving it on a District Line train.

The device's detonator went off, sending a fireball through the carriage, but it did not ignite the explosive.

Describing the moment it went off, prosecutor Alison Morgan: 'The partial explosion caused a large fireball. Some in the carriage were caught by the flames and sustained significant burns, many ran in fear and panic.

'They were fortunate - had the device fully detonated, it is inevitable that serious injury and significant damage would have been caused within the carriage. Those in close proximity to the device may well have been killed.'

Meanwhile Hassan had changed his clothes, donning a Chelsea football shirt, and was crisscrossing the South East on four different trains on his way to the port of Dover.

An alert border police officer spotted and challenged him before he could board a ferry to the continent.

He was found to have researched what happened to his bomb by looking up Parsons Green on the BBC website on his phone as he made his way to Dover. Radical material was found at his home.

A memory stick contained eight nasheeds- Arabic chants - which included the lines: 'O State of Islam attack the creed of kufr [infidels], and crush the soldiers' gang.

'Send torrents of terror, pull out slaughter, break the shackles, wage a battle that will make a child's hair go grey, scorch the bodies with a blazing fire, a sight never imagined before.'

His foster parents, Mr and Mrs Jones, knew nothing of his plans and were said to have been devastated by his actions.

In the days after the bombing, friends said the couple were considering giving up fostering.

The kind-hearted couple were awarded have MBEs in 2010 for fostering at least 268 people over three decades, many of whom came from some of the world's poorest countries.

Security Minister Ben Wallace said the Parson's Green attack revealed flaws in the government's anti-radicalisation programme.

He said: 'It is clear that there are some lessons to be learned in this particular case.

'The police and local council have conducted an internal review into how it was handled and we are working with our partners to review the findings and to identify where further improvements can be made.'

Did tube bomber slip through the net? The repeated warnings over 'angry' teenager's radical ideas Ahmed Hassan admitted he was trained to kill by Islamic State shortly after he arrived in Britain, yet managed to keep his bomb plot secret from authorities. The 18-year-old asylum seeker had already come to the attention of Home Office officials, the anti-terrorism Prevent organisation, social workers, mental health professionals and charities. Long before he set about making a home-made bomb, there were signs he was depressed, unstable, radicalised and bent on revenge on Britain for the death of his father, the court heard. In January 2016, three months after arriving in Britain illegally, he told Home Office officials he was recruited by ISIS and forced to train with them. Hassan is pictured in his bedroom at the foster home where he plotted his planned massacre During an immigration interview at Lunar House in Croydon, he said: 'They trained us how to kill. It was all religious based.' But he denied being sent to work for ISIS in Europe, the Old Bailey trial heard. While in the care of Barnardo's children's charity, he was caught listening to an Arabic song with a call to bring slaughter to people's homes. He was also seen to look at a picture of balaclava-clad fighters holding machine guns and the black ISIS flag. He told his mentor Katie Cable, from Brooklands College in Weybridge, how his mother was shot and his father was killed in an explosion. And he said he had a 'duty to hate Britain', the country he blamed for dropping the bomb. Hassan is presented with his 'student of the year' award at Brooklands College, Weybridge In the summer of 2016, Ms Cable saw a WhatsApp message on Hassan's phone saying: 'IS has accepted your donation.' She was so concerned that she contacted a civilian worker at the anti-terrorism Prevent organisation to report it. She said he had talked about Tony Blair and expressed 'anger' at events in Iraq. 'I believe the anger was very clear. He referred to being angry several times,' she said. In the days before the bombing, Ms Cable said she was worried about his mental state. Hassan scrawled 'bored, bored, bored' on his bedroom door on the summer he built the bomb Surrey County Council today admitted that their anti-radicalisation strategy was not up to scratch after Hassan claimed he had been trained by ISIS during his Home Office interview in January 2016. A Surrey County Council spokesman said: 'This was a difficult case in tough circumstances. 'We have a duty as a county council to provide support to unaccompanied asylum-seeking children who arrive in Surrey and we're also expected to work with law enforcement agencies and others to help stop people being drawn into terrorism. 'Our work with other agencies in this case wasn't as good as it should have been and we're sorry for our part in that. 'We knew before the terrible incident at Parsons Green that we needed to make changes and had already begun to do so. 'Since then we have made further improvements and continue to focus on ensuring our work in this area is as good as it can be. Our thoughts remain with everyone affected.' Hassan told immigration officials he had been 'trained to kill' by ISIS, but he claimed at trial that he made that up Commander Dean Haydon, head of Scotland Yard's counter terrorism command, said Hassan was 'devious' and hid his plot while appearing to engage with Prevent, the de-radicalisation programme. 'On the one hand he was appearing to engage with that programme but he kept secret what he was planning and plotting so we describe him as a lone actor,' he said. He said a review was underway of the Surrey Prevent scheme to look at whether any lessons could be learned. Barnardo's contacted the Counter Terrorism Unit and Prevent the day following Ahmed Hassan's immigration interview with the Home Office. A spokesman for the children's charity said: 'Barnardo's followed strict processes and procedures in swiftly alerting the appropriate authorities over security concerns to try and ensure they were dealt with properly.'

The mystery boy who said he had a 'duty to hate Britain': Bomber's web of lies mean questions still surround his past

By Nick Fagge and Duncan Gardham

Arriving in the UK at the age of 16, Ahmed Hassan's hatred of the West had been simmering for years.

Portraying himself as an orphan from Iraq whose mother was shot while his taxi driver father died in a bombing raid, there was sympathy for his plight.

But the teenager spun a web of lies from the moment he arrived in the UK on the back of lorry through the Channel tunnel two years ago.

He lied to UK immigration officials several times, disappeared on mysterious trips to Wales and had a secret social life hidden from his foster carers.

Even his true identity is in question with no record of a man bearing his name and date of birth found by Iraqi officials.

Hassan had arrived in the UK when he was 16 after he was smuggled through the Channel Tunnel without any identity papers

Timeline of Ahmed Hassan's movements 2006 - While a young boy in Iraq, he says his father was killed by a bomb. He grew up blaming 'Britain and America', the court heard. 2014 - ISIS begin to take over parts of Iraq and Syria. Hassan said he was taken into one of the group's training camps, but he later denied he had contact with the terror group and said he lived elsewhere in Iraq. 2015 - He crosses into Turkey, then comes to Britain via Italy and Calais's jungle camp. He got across the border in the back of a lorry. 2016 - His first immigration interview is carried out. He tells officers he was in an ISIS camp. He later claimed he made this up to avoid deportation. 2017 - He plants bomb on the London Underground then gets back to Dover where he planned to escape to France. Advertisement

Claiming he was born in June 1999 into a poor Kurdish family in Baghdad, Ahmed Hassan said he lost his mother to gunshot wounds shortly after the 2003 invasion.

Struggling to make ends meet his father, a taxi driver, forced the young boy and his brother to move frequently as he could not afford the rent.

Hassan missed a year of school because of the war, but boasted that he shined as a bright student when he started classes aged seven.

He described his devastatation when his father was killed in a US bombing strike in 2006 and he was then taken in by his uncle, moving out of the Iraqi capital to the provincial city of Jalawla, north east of Baghdad.

Hassan told the Old Bailey: 'I was told he [my father] died in an explosion while he was working as a taxi driver.

'He used to go to work and come back evenings and he just didn't come back. It was very difficult, I didn't understand much of what was going on, I was in a state of confusion.'

Hassan began earning money at the age of 12, loading and unloading vegetables from trucks at the Iraq-Iran border after school.

He left school aged 15, and when ISIS was at the height of its power he crossed the border to Turkey, boarded a ship to Italy, then a train to France where he joined the hundreds of migrants living in the chaos of Calais seeking a new life in Britain.

After two months in the notorious Calais Jungle, he slipped into the UK in October 2015 in the back of a lorry via the Channel Tunnel.

That same month he was placed in the care of Surrey County Council, who put him in a Barnardo's-run hostel, the Bay Tree, in Horley.

Here Hassan was spotted by two members of staff watching ISIS videos on Facebook and listening to a jihadi chant in Arabic saying: 'We are coming to you with slaughter, coming into your own home'.

And when questioned by Home Office officials the following January, he openly declared his association with Islamic State proclaiming; 'I was recruited by ISIS for three months.

'They trained us on how to kill and it was all religious based.'

However, he later claimed the terror group had taken him by force and threatened his uncle and brother before denying that he was an ISIS agent sent to Europe.

His foster mother, Penelope Jones, had received an MBE from the Queen for her fostering work

From the warzone of Iraq, Hassan was brought to this unassuming street in Sunbury, Surrey

He then changed his story again, claiming in court this month that he had made up a link with ISIS after learning in Calais that it would help his application for asylum in Britain.

Under cross-examination, the prosecution accused Hassan of being a 'proficient liar' after he admitted not telling the truth to immigration officials in 2016.

Hassan said: 'I never lied. I made up a story for the Home Office to accept me.

'Because I am from a wealthy safe area of northern Iraq and if I told the truth, my only reason to leave that country was to further my studies, I felt I had to make up something strong.'

In April 2016, Hassan was accepted at Brooklands Sixth Form College in Weybridge, Surrey, to learn English and prepare for further education.

He was placed in foster care, moving in with Ron and Penny Jones at their terrace house in Sunbury, Surrey.

Police closed down the foster family's entire street in the wake of the bombing last September

His behaviour was marked with violent mood swings – snapping pens and storming out of class – flashbacks, boredom and shakes – classic symptoms of trauma.

'It is my duty to hate Britain [because of what happened to my family],' he told his teacher and mentor Katie Cable, the Old Bailey heard.

However, he was seen as exceptionally bright and was awarded 'Student of the Year' after receiving distinction in nine pieces of work at the end of the 2015-16 academic year.

The court heard how, at college, Hassan had wanted to be a wildlife photographer and had aspirations of being the next David Attenborough.

Just weeks before priming his homemade bomb on a busy District Line tube he texted the teacher to complain about UK air attacks on ISIS positions in Syria and Iraq, saying: 'Your country continues to bomb my people daily.'

When Ms Cable saw a message on his phone from the Islamic State accepting a cash donation she reported him to the de-radicalisation programme Prevent.

Hassan was constantly talking on the phone and reading messages and would spend up to five-days away in Wales, visiting 'friends' he had met in the Calais Jungle.

But it was in his suburban foster home, while the caring couple who had taken in him were away on an August break to Blackpool, that Hassan built the terrifying bomb – stuffed with nails, bolts and screws - that he placed on a packed rush hour tube train in September last year to kill and maim in a warped act of revenge.
