The late Monday explosion killed at least 22 people, including children, and wounding at least 59 others. As of Tuesday afternoon, no organization claimed responsibility for the Manchester attack, though local police said that they were interrogating a British-born suspect.
The security service known as MI5, Britain’s national domestic intelligence agency, currently rates the threat from international terrorism as “severe” and the probability of an attack as “highly likely.”
Additionally, all three British intelligence agencies, MI5, MI6 and GCHQ, are undergoing expansions in response to the rise in the radicalization of young people through terrorist websites, and as hundreds of battle-trained fighters who joined jihadist groups in Syria and Iraq return home to Britain and the European continent.
While England has been targeted less frequently than its neighbors Belgium, France, and Germany, it has in recent years suffered a number of attacks, and remains a top target, given Britain’s part in the U.S.-led coalition against ISIS in Syria and Iraq.
Assistant commissioner Mark Rowley said that the UK police had thwarted 13 terror plots from far-right and Islamist extremists that were on the scale of those carried out in Paris, in which ISIS supporters targeted bars and clubs in a series of coordinated attacks.
