British foreign minister David Cameron said on Sunday he had "formally condemned in the strongest terms" Iran's attack on Israel in a call with his Iranian counterpart Hossein Amirabdollahian.

"I made clear that Iran must stop these reckless attacks, de-escalate and release the MSC Aries," Cameron said on X, referring to a Portuguese-flagged vessel that Iran's state news agency IRNA said had been seized by Revolutionary Guards.
