Iran attack targets U.S. Al Udeid Air Base in Qatar. Here's what to know about the military base.

Iran took action to retaliate against the United States on Monday, firing short- and medium-range missiles targeting the U.S. Al Udeid Air Base in Qatar. Qatar's government said the missiles were intercepted, and no casualties were reported, U.S. and Qatari officials said.

President Trump called the attack a "very weak response" that the U.S. expected and "very effectively countered." He said in a pair of social media posts that 14 missiles were fired, and he thanked Iran "for giving us early notice, which made it possible for no lives to be lost, and nobody to be injured."

Iran launched its missiles in retaliation for U.S. strikes targeting three Iranian nuclear sites over the weekend.
