Ariana Grande Concert Attack 2017

A man in the United Kingdom has been arrested after allegedly dressing up as the Manchester Arena bomber Salman Abedi for Halloween.

The head of Britain's security services said on Thursday he was profoundly sorry his spies had missed a "significant" opportunity to prevent a deadly 2017 suicide bombing at the end of an Ariana Grande pop concert in Manchester.

Britain's MI5 security service failed to act on two pieces of information ahead of an attack at an Ariana Grande concert in Manchester that killed 22 people in 2017, an official inquiry found Thursday.

Security teams at Britain's Manchester Arena "should have prevented or minimised" the impact of the 2017 terror attack at an Ariana Grande concert that killed 22 people, a public inquiry found Thursday.
