An Iranian drone and missile attack struck Kuwait's international airport early this morning, causing injuries and forcing authorities to divert flights, Kuwait's state news agency reported.
The attack caused "severe damage" to the airport's T1 building, the report said, citing the General Civil Aviation Authority.
The US military earlier said two Iranian missiles fired at Kuwait fell short or broke apart en route, and three missiles launched at Bahrain were intercepted by US and Bahraini forces.
US Central Command added that Iran launched ballistic missiles toward regional neighbours but all failed to hit targets.
US forces conducted strikes on Qeshm Island in response to attempted attacks by Iran and defeated multiple Iranian ballistic missiles and drones.
Since the conflict began in late February, Iran has repeatedly attacked targets in Bahrain and Kuwait, where US military bases are located.
Central Command said US forces also downed Iranian drones targeting civilian shipping in regional waters and carried out strikes on Qeshm Island near the Strait of Hormuz in response to the attempted attacks by Iran.
This was the latest of several such flare-ups.
More than three months after the US and Israel launched strikes against Iran, the conflict is stuck in a stalemate, with a ceasefire in place while the Strait of Hormuz remains largely shut to maritime traffic.
Iran and the United States said last week that they had reached a tentative initial agreement to halt the war. But the two sides have yet to sign off on the deal.
Iranian media reported that Iran has not communicated with the United States for several days, but US President Donald Trump said negotiations have not stopped.
"The conversations between us have been going on continuously, including four days ago, three days ago, two days ago, one day ago, and today," he said in a social media post.
Discussions on nuclear programme
Since mid-March, Mr Trump has repeatedly said he is close to a deal that would end the fighting and allow negotiators to tackle issues including the future of Iran's nuclear programme.
Mr Trump has said stopping Iran from acquiring nuclear weapons is his top priority.
Iran denies it is developing a nuclear bomb and said its atomic programme is for peaceful purposes.
Iran is seeking access to billions of dollars in oil revenues, waivers on crude exports, a lifting of a US blockade on its ports and continued leverage over the strait.
US Secretary of State Marco Rubio told politicians yesterday that the US would agree to sanctions relief only if Iran agrees to give up its nuclear activity.
Mr Rubio declared: "The war is over," during a sharp exchange with Democratic Senator Cory Booker of New Jersey, who disagreed.
