Israeli airstrikes hit Yemen's main airport as a civilian Airbus 320 with hundreds of passengers on board was landing and a U.N. delegation was waiting to leave, according to the U.N.'s top humanitarian official in Yemen. The airstrikes destroyed the airport control tower but the plane was able to land safely. At least three people were killed and dozens injured in the strike. Yemen's Houthi rebels have been attacking Israel, and Israel has escalated its response. The U.N. delegation, including WHO Director-General Tedros Adhanom Ghebreyesus, was able to depart for Jordan on Friday afternoon.
