The UAE is a member of a Saudi-led military coalition backing Yemen's internationally recognized government against Iran-aligned Houthis. But it has been scaling down its presence since June amid rising criticism of the war.
More than 100 UAE citizens have been killed in the war since the coalition intervened in March 2015 to try to restore the government of President Abd-Rabbu Mansour Hadi, which was ousted by the Houthis in late 2014.
