UK spy chief says Iran is stepping up targeting of military bases

The head of the United Kingdom’s domestic spy agency has said Iran is ramping up attempts to strike sensitive military targets after a series of incidents at airbases in Britain, even as Tehran has denied any involvement. In his annual speech, M15 Director-General Ken McCallum on Tuesday said there had been a major shift in Tehran’s calculus this year and that “Iranian ambitions to come at harder targets, like military sites”. McCallum’s warning came after UK Prime Minister Andy Burnham said Iran’s Islamic Revolutionary Guard Corps (IRGC) was “ almost certainly ” behind a suspected plot against Royal Air Force (RAF) Fairford, an airbase used by US bombers to carry out strikes on Iran.
