Over 250 Survivors of 2017 Ariana Grande Concert Bombing Sue MI5 for Negligence

The lawsuit claims MI5 missed critical opportunities to prevent the attack, which resulted in 22 deaths and over 100 injuries.

More than 250 survivors and relatives of the 2017 Manchester Arena bombing have filed a lawsuit against MI5, alleging the agency failed to act on crucial intelligence.
An inquiry last year found MI5 had significant opportunities to prevent the attack by acting on intelligence about bomber Salman Abedi.
MI5 head Ken McCallum publicly apologized, acknowledging the agency's failure to prevent the tragedy.
The lawsuit, a first of its kind against MI5, has been submitted to the UK’s Investigatory Powers Tribunal.
The legal action highlights ongoing concerns about intelligence handling and accountability in preventing terrorist attacks.
