Israeli attacks on the airport in Sanaa and the port of Al Hudaydah in Yemen have posed a danger to the WHO chief. The Houthi rebels accuse Israel of aggression, recalling previous attacks on Israel.

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.

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.
