WASHINGTON (AP) — The State Department says an American contractor who had been detained in Yemen is dead.

John Hamen was detained after arriving in the conflict-ravaged Arab country on a U.N. aircraft last month.

He was working for a company that manages U.N. facilities in the capital, Sanaa, which is controlled by Shiite Houthi rebels.

State Department spokesman William Cocks said Tuesday that Hamen died, but he provided no cause of death.
