Since Saudi-led coalition intervened in 2015, thousands of Houthi rebels have also been killed.
More than a dozen soldiers from Saudi Arabia have been killed in Yemen during operations along the border. This brings the total number of Saudi casualties since 2015 to over 1,000, according to state media.
Meanwhile, the humanitarian crisis in Yemen is worsening as the war prevents much-needed aid from reaching many Yemenis. The UN estimates that 22 million Yemenis are in need of food aid and more than eight million are threatened by severe hunger.
