Israel has carried out its first strikes against Houthi targets in Yemen since the Israel-Iran ceasefire, attacking ports and a power plant around midnight local time Sunday night into Monday morning.

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.

The attack on the Eternity C, which also killed at least three of the crew, represents the most serious assault carried out by the Houthis in the crucial maritime trade route.
