MI5 Director General Ken McCallum stated that the agency is allocating more resources to countering state threats than it did during the Cold War, marking a significant shift in operational priorities. McCallum explained that state-sponsored and terrorist threats now represent missions of equal scale for the British intelligence service. This strategic adjustment comes as the U.K. confronts escalating hybrid attacks from Iran and Russia, which are increasingly targeting infrastructure and societal cohesion. The agency has reported that Iran-linked operations resulted in over 50 arrests within the last year, while Russia remains the primary hostile state threat.

Background

U.K. authorities identified Iran’s Islamic Revolutionary Guard Corps as likely responsible for a foiled plot targeting RAF Fairford, an air base used by the U.S. military.
Seven men were questioned in connection with the Fairford incident and subsequently released on bail, though U.K. officials do not believe Iran possesses the capability for such an elaborate attack on British soil.
McCallum noted that Iran typically employs criminal proxies recruited online to conduct operations in the U.K., a method he described as lacking high sophistication.
The U.K. is establishing a new AI threat-assessment center to address concerns about artificial intelligence being used for radicalization, attack planning, and bioweapons acquisition.
