US official says some at Qatar’s Al Udeid Air Base advised to evacuate as Iran official brings up earlier attack there

Some personnel have been advised to leave the U.S. military's Al Udeid Air Base in Qatar by Wednesday evening, three diplomats told Reuters, amid warnings from Washington that it could intervene to protect protesters in Iran.

The U.S. embassy in Doha had no immediate comment and Qatar's Ministry of Foreign Affairs did not immediately respond to a Reuters request for confirmation or comment.

Al Udeid is the Middle East's largest U.S. base, housing around 10,000 troops.
