MI5 warns Iran, Russia escalating hybrid campaigns against UK targets

MI5 confirms a significant escalation in Iranian state-sponsored threats against the UK, including violent plots and intensified targeting of military bases. This marks a shift from previous activity, with Iran now actively plotting attacks and expanding its hybrid warfare efforts. The specific nature of all plots and incidents remains largely undisclosed, but the attribution to Iran and its IRGC is consistent across UK official statements.

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.
