London, Thanasis Gavos

More than 250 injured survivors of the terrorist attack in Manchester Arena in May 2017 appeal to British justice against the MI5 security service.

In the bomb attack at the end of Ariana Grande’s concert with the perpetrator 22-year-old Salman Abedi, 22 people were killed and hundreds were injured.

The lawsuit by the survivors comes after an independent inquiry found that the deadly attack could have been prevented if MI5 had acted properly on security intelligence it had received about the attacker months earlier.

Two specific pieces of information of concern about the perpetrator had been reviewed and determined to be non-terrorism related.

The finding resulted in a rare public apology from MI5 director-general Ken McCallum to relatives of victims and survivors.

Andrew Roussos, the Cypriot-born father of the attack’s youngest victim, eight-year-old Safi-Rose, has said his daughter would still be alive “if MI5 had done their job” and stopped the attacker.
