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, the U.N.'s top humanitarian official in Yemen said Friday.

Israel has banned the pan-Arab Al Jazeera network and accused six of its Gaza reporters of being militants. The Qatar-based broadcaster denies the allegations and accuses Israel of trying to silence its war coverage, which has focused heavily on civilian casualties from Israeli military operations.

Israeli forces unleashed a series of strikes on the Yemeni capital Sanaa and the western city of Hodeidah on Thursday, killing at least six people and injuring dozens more, the Houthi militant group said in a statement.
