US base Qatar evacuation Iran protests.

A U.S. official says some personnel at a key U.S. military base in Qatar have been advised to evacuate. The decision to evacuate by Wednesday evening comes as a senior official in Iran brought up an earlier Iranian attack there. The U.S. official won’t go into further details about the move. Qatar says the measures are in response to “regional tensions.” It comes as anti-government protests in nearby Iran continue and President Donald Trump has said he’s willing to conduct military operations in the country if the government continues to retaliate against the protesters. The base hosts thousands of U.S. service members and was targeted by Iran in June in retaliation for U.S. strikes on its nuclear facilities.
