DUBAI, United Arab Emirates — The United Arab Emirates says one of its soldiers has been killed while serving in the Saudi-led war in Yemen.

A short military statement Thursday on the state-run WAM news agency announced the soldier's death, without offering a cause.

The UAE is one of Saudi Arabia's main allies in its war against Yemen's Shiite rebels, known as Houthis.

The war in Yemen has killed more than 10,000 civilians and displaced over 3 million people. It began when the Houthis and allied military units loyal to a former president 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.

The war has ground into a stalemate. Peace efforts by the United Nations have faltered.
