Israel’s military launched airstrikes early Monday targeting ports and facilities held by Yemen’s Houthi rebels, with the rebels responding with missile fire targeting Israel.

Israel carried out it 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 says it has launched strikes on Houthi targets in three Yemeni ports, including the western port of Hodeidah, Ras Isa and Saif. The attacks come shortly after the Israeli military issued evacuation orders for civilians in the areas, warning of imminent air strikes.
