By Andrew Mills, Parisa Hafezi and Alexander Cornwell DOHA/ISTANBUL/TEL AVIV (Reuters) - Iran's military said on Monday it had carried out a "devastating and powerful" missile attack on the Al Udeid U.

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,

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