Israeli air strikes struck Sanaa’s international airport and other targets in Yemen on Thursday, killing six people.

The World Health Organization, WHO, chief Tedros Adhanom Ghebreyesus, who said he was at the airport during the strike, added that one of their plane’s crew members was injured.

However, the Israeli military did not immediately respond to a request for comment on whether they were aware of his presence at the time.

The strikes targeting the airport, military facilities and power stations in rebel areas follow rising hostilities between Israel and the Huthis, part of Iran’s axis of resistance alliance against Israel.
