DUBAI, United Arab Emirates (AP) — A Liberian-flagged cargo ship attacked by Yemen’s Houthi rebels sank Wednesday in the Red Sea, with a European naval force in the Mideast saying that only six of 25 people who were on board have been rescued.

At least three of the 25 people on board the Eternity C were killed after it was attacked by the Iran-backed group.

Six mariners, five of them Filipinos and an Indian, have been rescued after a deadly attack on a cargo ship that sank off rebel-held Yemen, an EU maritime force said Wednesday, as the search continued for the rest of the crew.
