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 Iran-backed Houthis said in a statement where it vowed to retaliate.

The head of the World Health Organization (WHO) and other UN staff were at Yemen's international airport in Sanaa on Thursday during Israeli air strikes which are reported to have killed at least six people. WHO Director General Tedros Adhanom Ghebreyesus said they were about to board a plane when the attacks began.

The head of the World Health Organization said Saturday he only narrowly escaped death in fatal Israeli strikes on the airport in Yemen's Huthi rebel-held capital.
