MI5 chief warns Iran is targeting military sites in UK as hostile state threats surge

Iran is trying to hit military sites in the UK and the suspected plot to attack a US-run military airbase in September was “not unique”, the head of Britain’s MI5 spy agency said on Tuesday. Ken McCallum, who leads the UK’s domestic security service, said Tehran was seeking to intensify its attacks in Britain beyond the traditional targets of Iranians opposed to the country’s Islamic authorities.
