More than 250 survivors of the bombing that killed 22 people at an Ariana Grande concert are taking legal action against the U.K.'s domestic intelligence agency.

An inquiry has found that Britain’s domestic intelligence agency missed a significant opportunity to prevent the suicide bombing that killed 22 people at a 2017 Ariana Grande concert in northwest England.

A jury in London has concluded that a terror attack in the south of the city last year could have been prevented had the perpetrator been recalled to prison after he bought items that were used in a fake suicide belt.

A public inquiry into a mass attack at a 2017 Ariana Grade concert in northwest England has found that “serious shortcomings” by venue operators, security staff and police helped a suicide bomber who killed 22 people carry out his “evil intentions.”.

LONDON The brother of the suicide bomber who set off an explosion at a 2017 Ariana Grande concert in Manchester, England, killing 22 people and injuring hundreds, was sentenced Thursday to a minimum of 55 years in prison. Hashem Abedi, 23, had denied helping plan the attack at Manchester Arena but was found guilty of murder, attempted murder, and conspiring to cause explosions. His elder brother Salman Abedi, who set off the bomb, died in the May 22, 2017 bombing at the end of the concert. The defendant should clearly understand the minimum term he should serve is 55 years. He added that there was a significant degree of premeditation and that the motivation for the brothers was to advance the ideology of Islamism.
