DUBAI, United Arab Emirates (AP) — 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.

Yemen's Houthi rebels killed 3 mariners with an attack on a ship in the Red Sea, a European naval force says, fueling concern over a possible new wave of attacks by the Iran-backed group.

A Liberian-flagged cargo ship came under fire on Monday in the Red Sea, with two security guards on board reportedly hurt and two others missing in an assault that came after Yemen's Houthi rebels purportedly sunk another vessel in a similar attack.
