The UK declined to say whether it believes US-Israeli strikes on Iran are legal as missile attacks continued across the Middle East on Sunday. Explosions were heard in multiple Gulf states as Iran vowed to carry out its "most intense operation" ever in retaliation for the killing of Supreme Leader Ayatollah Ali Khamenei. The UK has played no part in the US-Israeli strikes, but Defence Secretary John Healey warned on Sunday that Iranian retaliation could put British personnel and allies at risk.
