A teenage asylum-seeker, who was arrested in Dover after setting off a bomb on a rush hour tube train in west London, has been jailed for life.

18 year-old Ahmed Hassan, who was born in Iraq, will serve a minimum of 34 years behind bars after being found guilty of attempted murder following the attack at Parsons Green last September.

Hassan, of Sunbury, Surrey, was sentenced today at the Old Bailey.

A jury unanimously convicted him of attempted murder last Friday.

He had set off the bomb on Friday, September 15 last year and was arrested at Dover Eastern Docks the next morning as he tried to leave the country.

The court had heard that passengers caught up in the blast were left with mental and physical scars.

The explosion injured 30 passengers who suffered burns to their faces, lips, ears, noses, eyebrows and lost hair or were injured in the panic as commuters fled.

The nail bomb packed with homemade "Mother of Satan" TATP explosives only partially exploded.

Hassan had told immigration officials he was "trained to kill" by IS when he tried to blow up the rush hour commuter train with the 400g high explosive and shrapnel bomb.

He left it on a District line train and got off at Putney Bridge station.

The bomb partially exploded a stop later at Parsons Green, west London, at about 8.20am, sending a fireball flying through the carriage.

Hassan bought some of the ingredients using a £20 Amazon voucher he received for being 'student of the year' at Brookland's College in Weybridge, Surrey.

During Hassan's sentencing hearing victim impact statements were read out.

Wearing a dark green jumper and white shirt and flanked by three dock officers Hassan showed no emotion, hung his head as he heard the devastating psychological effects of the blast on his victims.

Lucinda Glazerbrook was standing near the blast and suffered burns to her forehead, lips, ears and hands, as well as losing some of her hair.

She said in a statement read by prosecutor Alison Morgan: "I have been diagnosed with PTSD, anxiety and severe rage.

"I have struggled with intense memories of the incident in which I believed I was going to die.

"I regularly relive the traumatic experience of the explosion and feel I have changed as a person.

"I relive the distressing images of burns to people's faces from the explosion that are triggered if I travel in crowded public transport."

Stephen Nash, who suffered facial burns, said he had to give up his job because he could not longer travel to London.

He added: "I have had trouble sleeping due to anxiety. I believed I was going to die.

"I do not travel in to London any more, being in crowds brings it all back. If I hear loud noises it makes me jump.

"I was working in London but had to give up my job because I can no longer travel on crowded trains.

"Being in public places causes me to relive the incident. I believe it will be with me the rest of my life."

Another woman, who suffered burns to her thigh, face and hands, suffered 13 per cent burns to her back and was left with scarring which could take two years to heal.

Yahya Farroukh, who lived in the same foster home as Hassan, said he fear retaliation after being wrongfully implicated as his accomplice.

The 21-year-old was arrested after Hassan told officers he accompanied him to Dover, before being released without without charge.

Ms Morgan said: "As a result of what was said about him he says he has suffered health problems, both physical and mental.

"He is generally nervous about what people may say about him due to the widespread newspaper reporting about him.

"He describes the impact as making him feel scared all the time and not sleeping well."

During his trial prosecutor said he carried out the attack as he blamed the UK for his father's death in Iraq.

But he denied trying to kill people, claiming it was all part of a "fantasy" because he bored and wanted attention.

He had been inspired by action movies and hoped to become a fugitive chased across Europe by Interpol.

He maintained he only wanted the device to burn, not explode.

Ms Morgan said it was "only a matter of luck" the bomb did not work properly.

She said: "The prosecution's case is that this was an act intended to cause mass murder on a crowded London underground train.

"The fact this offence has terrorist connections is not in dispute, it is the basis of the prosecution's advance of the case.

"The fact no charges of terrorism were lodged does not mean it cannot be treated as a terrorist act.

"Some of the most serious terrorist offences were in fact charges of conspiracy to murder or attempted murder.

"Given the force of the explosion if it had been detonated the impact of the shrapnel, those in the immediate vicinity would have suffered serious harm if not death."

The court heard Hassan also lied about his date of birth and so may not be 18.

Jurors were told Hassan arrived in Britain in the back of a lorry in October 2015, and later told Home Office officials IS had trained him to kill.

He said he was smuggled from Turkey into Italy, and made his way to Calais where he spent two months in the 'Jungle' migrants camp.

Hassan was eventually placed with foster carers Ron and Penelope Jones in Sunbury.

But Hassan began plotting a bomb attack during the summer holidays last year and had components delivered while his foster parents were on holiday in Blackpool.

One witness heard him listening to a 'call to arms', encouraging "slaughter in this homeland", while another had seen Hassan watching a video of fighters with an IS flag.

A memory stick found on his chest of drawers contained 'nasheeds', involving one talking about a "night of revenge and noble slaughter".

He claimed he had tested the TATP explosive in a Coca-Cola can on the kitchen table the day before leaving it on the tube.

His mother died when he was young and his taxi driver father was killed in an explosion in Baghdad when Hassan was aged seven, he said.
