British Foreign Secretary David Cameron said on Sunday he had made clear in a call with Iranian Foreign Minister Hossein Amirabdollahian that Iran shared responsibility for preventing Houthi attacks in the Red Sea.
"I made clear that Iran shares responsibility for preventing these attacks, given their long-standing support to the Houthis," he said in a post on social media site X, adding that the attacks "threaten innocent lives and the global economy".
US Navy helicopters sank three of four small boats used by the Houthis to attack a merchant vessel in the southern Red Sea on Sunday, US central command (CENTCOM) said on X.
Helicopters from the USS Eisenhower and USS Gravely, responding to distress calls from the Maersk Hangzhou, returned fire on the Houthi boats in self-defense and sank three of the vessels with no survivors.
The fourth boat fled the area.
