MI5 spy chief says Russia and Iran are behind a 'staggering' rise in deadly plots

LONDON (AP) — Britain is facing a “staggering rise” in attempts at assassination, sabotage and other crimes on U.K. soil by Russia and Iran, as the two states recruit criminals to “do their dirty work,” the head of Britain's domestic intelligence agency said Tuesday.

MI5 Director General Ken McCallum said his agents and police have tackled 20 “potentially lethal” plots backed by Iran since 2022 and warned that it could expand its targets in the United Kingdom if conflicts in the Middle East deepen.

So far, the threats have been aimed at Iranians abroad who oppose the country's authorities. But McCallum said there is the risk “of an increase in — or broadening of — Iranian state aggression in the U.K.” if the Middle East crisis escalates with Israel launching a major attack in response to Iran’s recent missile barrage.

In a rare public speech setting out the major threats to the U.K. from both states and militant groups, McCallum argued that hostile states, radicalized individuals and a revived Islamic State group have combined to create “the most complex and interconnected threat environment we’ve ever seen.”
