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.

The head of the World Health Organization said he was about to board a flight in the Yemeni capital when the airport came under bombardment.

Director-General of the World Health Organization, Tedros Adhanom Ghebreyesus, says he was close to the departure lounge when it was hit.
