The Parsons Green bomber was today convicted of attempted murder after his device partially detonated at the London tube station a year ago.
Hassan created and planted the bomb which went off at Parsons Green tube station last September, leaving several people injured. Police say 28 more were hurt in a panicked rush to leave the train.
Speaking in a quiet voice with a bowed head, Hassan, small and slight in frame, said he was born in Iraq's capital Baghdad in June 1999. Prosecutor Alison Morgan told jurors it was just "a matter of luck" that the bomb didn't fully detonate.
The device contained 400 grams, or almost a pound, of high explosives and 2.2 kilograms, or about five pounds, of shrapnel, the court was told, but Mr. Hassan, argued that he was "certain" the bomb would not explode. He told the court he only wanted to cause a fire because "he was bored and stressed" and fantasized about becoming a fugitive. He ordered hydrogen peroxide and other chemicals to make the explosive TATP, and bought nuts, bolts and knives for shrapnel at supermarkets.
One of the Jones' former foster children said Hassan did not really speak about his friends but was "constantly on the phone to them".
British authorities have been criticized for failing to foresee that Hassan, who had shown signs of depression and trauma, might act violently.
He had claimed asylum and was living with a foster family near London and attending a college before the attack.More news: Fortnite Mobile iOS common issues, and how to fix them
Ahmed Hassan deceived mentors who were trying to persuade him to turn his back on extremism and his case was never flagged to MI5 even though he told immigration officials that he had been trained to kill by Islamic State.
The train carriage was packed with more than 90 passengers at the time of the explosion. How he could put that on a train and think it wasn't going to kill people? "It was all religious based", he said.
Katie Cable, a lecturer at the college where Hassan studied, testified that Hassan blamed Britain for the death of his parents in Iraq.
Mr Haydon said Hassan appeared to engage with the de-radicalisation program, "but he kept secret what he was planning and plotting".
The trial heard that he had been reported to the Government's Prevent counter-extremism programme by social services and teachers who saw him receive a message about a "donation to IS" and listening to jihadi songs.
Hassan will be sentenced next week.
But his flight ended 24 hours after the blast when he was arrested at Dover. He faces a maximum of life in prison.
