A joint US–Israeli strike on Iran overnight has triggered retaliatory missile attacks from Tehran, raising fears of a wider regional escalation.

Iran’s Supreme Leader Ayatollah Ali Khamenei was killed in the strikes - a claim Iran denied until half an hour ago, with officials saying he was “safe and sound” and “actively commanding the field”.

International reaction has been mixed, with some governments condemning the strikes, others urging restraint, and many calling for urgent diplomatic talks.
