The Yemeni group, which has not claimed responsibility for the attack, says Israel-linked ships are ‘legitimate target’.

An attack by Yemen's Houthi rebels on a Liberian-flagged cargo ship in the Red Sea killed three mariners and wounded two others, a European Union naval force said Tuesday, highlighting the danger of the group's renewed campaign targeting a key maritime route for international trade.

Rescuers pulled six crew members alive from the Red Sea after Houthi militants attacked and sank a second ship this week, while the fate of another 15 was unknown after the Iran-aligned group said they held some of the seafarers.
