One person has been killed and several others injured in the latest Iranian drone strike on the airport in the Kuwaiti capital, Kuwait's Foreign and Defence Ministries said on Wednesday.
There was also severe structural damage in the passenger area of the airport's Terminal 1 building. The injured received medical treatment.
The armed forces were ready to take "any steps" necessary to protect the security and stability of the small Gulf state, he said.
The civil aviation authority said all flights scheduled for Wednesday had been suspended or diverted to other airports.
Iranian missiles and drones had struck the airport building and damaged several facilities, the authority said, according to the state news agency KUNA. An emergency plan had been activated at the airport, it said.
Air traffic across the Middle East had already been severely disrupted in recent months as a result of the Iran war. In March, hundreds of thousands of travellers were stranded in the region and some were flown home on evacuation flights.
The Gulf state had reported fresh Iranian attacks overnight. The US military said it had intercepted a "wave of Iranian drones" that had targeted US military facilities in the country. Kuwait has been among the hardest-hit countries in the war, including its airport in Kuwait City.
