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.

Yemen's Iran-backed Huthi rebels claimed responsibility Wednesday for a deadly attack that sank a merchant vessel earlier this week, their second attack on Red Sea shipping in 24 hours as they resumed their campaign in the key waterway.
