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

The Pentagon already had begun taking measures to strengthen its firepower in the Middle East and protect U.S. bases there.

Iran announced it had launched missiles at a US base in Qatar Monday in retaliation for American strikes on key nuclear facilities, with US President Donald Trump shrugging off the response as “very weak” and saying it was now time to make peace.
