Qatari forces participated in joint military exercises that ended in Saudi Arabia this week, in an apparent sign of some compromise among U.S.-allied Arab states locked in a nearly year-long dispute.

Reuters reported.

Saudi Arabia, the United Arab Emirates, Bahrain and Egypt cut diplomatic, trade and transport ties with Qatar last June, accusing it of supporting terrorism.

The United States, which has military bases in both Qatar and some of the countries lined up against it, is trying to mediate the feud. Washington said in October it was scaling back involvement in some joint military drills in the region following the rift.
