The United States has reportedly advised some military personnel to leave the Al-Udeid Air Base in Qatar by Wednesday evening, three diplomats told Reuters as Washington and Doha have yet to publicly comment on the reports. The report comes amid growing concerns over a possible U.S. attack on Iran. Al-Udeid Air Base, the largest U.S. military post in the region, was attacked by Iran in June last year in retaliation for strikes by the U.S. against key nuclear sites. | Doha News
