UK Intelligence Chief Warns Iran Shifting Attacks to Harder Targets

In October 2026, UK intelligence officials warned that Iran is seeking harder targets for attacks abroad. The MI5 chief said Iran is targeting military sites and that a suspected plot at RAF Fairford is not unique. Iran and Russia are stepping up hybrid campaigns in Britain, the spy chief said. Britain blames Iran's IRGC for an attempted terror plot that forced U.S. bombers out of the UK. A minister said Iran's role in the RAF Fairford incident affects Estonia's security.
