MI5 Chief Warns Iran Targeting UK Military Sites

Iran has significantly escalated its targeting of UK military bases, with MI5 reporting 50 arrests in the past year to disrupt Iran-linked operations. UK Prime Minister Andy Burnham and MI5 Director General Ken McCallum have publicly attributed a suspected terror plot at RAF Fairford to Iran's Islamic Revolutionary Guard Corps (IRGC), prompting a diplomatic warning from 30 nations and the summoning of Tehran's ambassador. This marks a qualitative shift in Iranian hostile operations against the UK, moving beyond espionage to include direct threats against military infrastructure.

MI5 Director General Ken McCallum has confirmed a qualitative shift in threat posture, with Iran intensifying attempts to target UK military sites and Russia escalating hybrid warfare against Ukraine's allies, including the UK. This represents the highest volume of state-linked threats since the Cold War, with specific incidents of Iranian attempts on UK military sites remaining undisclosed.
