President Trump has indicated that the U.S. was given prior warning of the Iranian strike. U.S. and Qatari authorities said the missiles were intercepted.

Qatar has some of the world's most advanced air defenses and said they "successfully thwarted" an Iranian missile attack.

Qatar's prime minister said on Tuesday relations with Iran have been scarred by an Iranian missile volley at a U.S. airbase in the Gulf Arab state, but that he hoped ties would eventually "come back to normal".
