The UAE is one of the main allies Saudi Arabia has in its war in Yemen against Shiite rebels known as Houthis and their allies.
The war in Yemen has killed more than 10,000 civilians and displaced over 3 million people. It began when Houthis seized Yemen's capital, Sanaa, in September 2014.
The Saudi-led coalition began its campaign in March 2015 in support of Yemen's internationally recognized government.
