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 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.

Israeli Defense Forces struck three ports in Yemen, alleging that the ports are used by the Houthi forces to "transfer weapons from the Iranian regime."
