The US has a key military base in Qatar, the Al Udeid Air Base, which serves as the headquarters of United States Central Command.

President Trump said Monday the Iranian government offered "early notice" about a series of missile strikes that targeted the U.S. Al Udeid Air Base in Qatar, downplaying Iran's response to the U.S. bombing of three Iranian nuclear sites over the weekend as "very weak."

Iran retaliated against the U.S. on Monday, launching missiles at a U.S. base in Qatar, according to a U.S. defense official and a statement from the Qatar foreign ministry. The missiles targeted Al Udeid Air Base outside Doha and were intercepted by air defenses before they could strike the base,
