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.

Houthi rebels in Yemen attempted to strike Israel’s Ben Gurion airport after sinking two vessels in the Red Sea this week, as the group ramps up its military pressure in support of Palestinians under Israeli fire in its bid to bring the war in Gaza to an end.

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.
