A crew in the Red Sea was forced to abandon ship after it was hit by Yemen’s Houthi rebels on Sunday, the first attack of its kind since President Trump announced a truce in May after he said the group promised to stop attacking Middle Eastern waterways.

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

Houthi attacks on a commercial vessel in the Red Sea follow Israeli strikes on Yemen's ports, heightening regional tensions.
