The Saudi and Emirati-led coalition has conducted air strikes on Yemen's Hudaida airport to support forces attempting to seize control from Houthi fighters inside, according to Saudi and Houthi media. The coalition warplanes carried out five strikes on the port city of Hudaida - a lifeline to millions of Yemenis - on Sunday in a continuation of the biggest battle of the war in three years, the Houthis' official SABA news agency said. Saudi-owned broadcaster Al Arabiya also reported strikes on the airport. The coalition launched a major offensive five days ago that could cut off supply lines to the capital Sanaa, which is controlled by the Houthis. Each side holds various parts of the airport.
