Houthi rebels in Yemen have launched a violent new wave of attacks on ships in the Red Sea, sinking two vessels and killing crew members.

The latest escalation follows a series of maritime attacks by the Houthis. On Tuesday, the group struck and sank the Eternity C, with 25 crew members onboard.

Israel struck Houthi targets at three Yemeni ports and a power plant overnight, in the country’s first attack on Yemen since the Israel-Iran ceasefire.
