After revelations that the bomber responsible for the deaths of 22 people attending an Ariana Grande concert in Manchester, England last week was known to UK authorities prior to the attack; but not under active investigation, MI5 has announced an internal review of how it handles intelligence regarding potential terrorists.

According to Interior Minister Amber Rudd, a review of intelligence procedures is a “right first step” for the nation’s intelligence agency to take in the wake of the tragic bombing.  It comes as no surprise that MI5 would assess its ability to prevent such attacks from occurring after one has been successfully carried out on UK soil, but it is far less common for the agency to openly address its decision to conduct such a review.  MI5 is traditionally tasked with countering terrorism and espionage within the UK and is subject to scrutiny from a committee of parliament, though they rarely make such scrutiny public.

“The review will look at what was known about Abedi, what decisions were made about the intelligence and what, if anything, could have been done differently,” a source from within MI5 said, speaking on condition of anonymity.

“This is a review that would seek to answer whether there are lessons to be learned from how the Security Service handled the intelligence on Abedi.”
