A Defense Department official is confirming a missile attack from Iran on a U.S. military base in Qatar but says no casualties have been reported. The official said Monday that Al Udeid Air Base was attacked by short-range and medium-range ballistic missiles. The U.S. is continuing to monitor the situation, said the official.

Iran announced the attack on state television as martial music played. A caption on screen called it “a mighty and successful response” to “America’s aggression.”
