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.

The head of the World Health Organization said on Friday he was not sure he was going to survive an air strike on Yemen's main airport carried out by Israel a day earlier during a series of attacks on the Iran-aligned Houthi movement.

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.
