How many times have we seen this scenario play out? How many more times?
Manchester, England (CNN)The 22-year-old behind the deadly bombing at an Ariana Grande concert in Manchester was known to security services, British Home Secretary Amber Rudd said Wednesday, as the country elevated its terror threat to the highest level for the first time in a decade.
Police have named Salman Abedi, a British-born national of Libyan descent, as the bomber in the attack on Manchester Arena, which killed at least 22 people, including children. Abedi died in the blast, in what appears to have been a suicide bombing.
Rudd confirmed in an interview with the BBC that Abedi was on the radar of intelligence services and that he had recently returned to the UK from Libya.
