A drone attack by Iran on a Kuwait targetted fuel tanks at Kuwait international airport, sparking a fire early on Sunday morning.
Kuwait authorities said that firefighters were working to contain the blaze.
The military said that it responded to a wave of hostile drones that violated the country's airspace on Sunday morning. About 15 drones were reportedly intercepted and destroyed in Saudi Arabia.
The Kuwait National Oil Company announced a precautionary cut to its crude oil production due to the attacks.
It called the drone attacks "a direct targeting of vital infrastructure."
Another statement by Kuwait said that civilian facilities suffered material damage due to falling fragments and debris.
The Kuwait government also said that the country's Public Institution for social security was targetted in an attack. Visuals on social media showed a tall building on fire.
Kuwait also said that two border security personnel were killed while on duty, and said attacks on its international airport and social security office caused fires.
Attacks were also reported across Saudi Arabia, the United Arab Emirates, Qatar and Kuwait.
The UAE’s defence ministry said that air defences were responding to “incoming missiles and drone threats from Iran.”
Qatar’s defence ministry said that the country was targeted a day earlier by 10 ballistic missiles and two cruise missiles fired from Iran, but most of them were intercepted and caused no casualties.
Dubai authorities said on Sunday that a Pakistani man was killed by debris from an “aerial interception.”
