Qatar said it successfully intercepted the missiles and no casualties were reported. It wasn't immediately clear if there was damage to the Iraq base.

Iran launched missiles at U.S. bases in Qatar and Iraq, officials said. Videos filmed by residents in Qatar showed flashes and explosions about an hour after the country announced it had closed its airspace ahead of an anticipated Iranian strike.

The White House and Defense Department are aware of, and closely monitoring, potential threats to the Al Udeid Air Base in Qatar, a senior White House official confirmed.
