The search for those missing after Yemen’s Houthi rebels sank a ship in the Red Sea has ended as at least four people are presumed dead and 11 others remain unaccounted for.

Yemen's Houthis sank two cargo ships in the Red Sea this week, the first flare-up in seven months in the Iran-backed group's years-long campaign to choke global shipping in protest over the war in Gaza and the plight of the Palestinians.

A total of 10 crew members have been rescued so far after Yemeni militants sank a Greek-owned cargo ship in the Red Sea.
