Salman Abedi allegedly killed 22 people in the bombing at Manchester Arena in May 2017
MPs reviewing the 2017 terror attacks say MI5 has accepted it made a mistake in not tracking the Manchester bomber. A report by the Intelligence and Security Committee said MI5 recognised it had moved “too slowly” to establish how dangerous Salman Abedi, 22, was. The security service had cause to monitor Abedi’s return to the UK from Libya days before the attack in which 22 people died, the report said. …
Abedi is believed to have been taught bomb-making while in Libya, before returning to Manchester in May last year to construct his device. He walked into the foyer of Manchester Arena, where thousands had been watching US singer Ariana Grande perform, and blew himself up. A previous report into the attack revealed that MI5 had planned to review the risks posed by Abedi – but the meeting was not scheduled to take place before the attack occurred.
In its findings, the ISC said there had been “no follow-up action” after Abedi visited a jailed terrorist organiser from Manchester. Last December, an independent assessment of MI5’s own secret review of the attack revealed for the first time that an opportunity had been missed to monitor Abedi’s movements – which would have revealed his return to the UK from Libya, days before he struck. “MI5 have since admitted that given the information they had on Abedi, they should have done so”, said the committee. …
The committee said one failing it had identified was so sensitive, it could not be shared publicly.
What was that failing? Let me guess. The BBC article does not mention the biggest scandal in MI5’s role in the bloody Manchester crime. That, in 2011, MI5 sent Salman Albedi to NATO’s war on Libya to serve as a child soldier. That bloody war completely fucked up Abedi’s mind; which resulted in his Manchester concert attack.
Mr Hibbert, who was left paralysed by the explosion, welcomed the report’s release. His daughter was also wounded as they left the arena when the bomb went off….
Another survivor, Robby Potter, who took his 11-year-old daughter Tegan to the concert, said he was considering taking legal action against MI5. His injuries from 37 pieces of flying shrapnel have meant he’s been unable to return to his job as a drainage engineer, and now drives lorries.
