LONDON (AP) 鈥� A legal claim against Britain鈥檚 domestic intelligence agency by more than 300 survivors of a bombing that killed 22 people at a in Manchester was rejected Friday by a special tribunal.
Judges on the U.K.鈥檚 Investigatory Powers Tribunal said the claimants waited too long to bring their case, which alleged that MI5 violated their human rights by failing to take measures that could have prevented the disaster.
Suicide bomber Salman Abedi set up a knapsack bomb in Manchester Arena at the end of Grande's concert on May 22, 2017, as thousands of young fans were leaving. As well as the 22 dead, more than 100 people were injured, many of them children and teenagers. Abedi died in the explosion.
An official that MI5 didn鈥檛 act swiftly enough on key information and missed a significant opportunity to prevent the bombing, the deadliest extremist attack in the U.K. in recent years.
Abedi had been a 鈥渟ubject of interest鈥� to MI5 officials in 2014, but his case was closed shortly after because he was deemed to be low risk.
The report also found one MI5 officer considered intelligence about Abedi to be a possible national security concern, but didn鈥檛 discuss it with colleagues quickly enough.
Ken McCallum, the head of MI5, said in a rare televised statement that he was 鈥減rofoundly sorry鈥� his agency was unable to prevent the attack.
Justice Rabinder Singh said the tribunal was 鈥渃onscious of the horrendous impact of the atrocity鈥� on the victims but said it would not be fair to let the claims proceed when they could have been filed sooner.
鈥淎ny reasonable person would have sympathy for them," Singh said. 鈥淭he grief and trauma which they have suffered, particularly where young children were killed, is almost unimaginable."
Singh also noted that if the case had proceeded it would have taken MI5 away from its core mission.
Three law firms representing the victims said in a statement that the ruling was 鈥渆xtremely disappointing.鈥�
"Our clients have had to endure continued delays but have done so with great patience and understanding in the hope that by allowing all legal processes to be fully explored, transparency and justice would be achieved,鈥� the statement said.
