Kuwait's army said on Thursday that its air defences were intercepting hostile missile and drone threats, but did not say where they were coming from.
The army said any sounds of explosions heard in the country were the result of air-defence systems intercepting the threats, and urged people to follow security and safety instructions issued by authorities.
The statement came after U.S. strikes earlier on Thursday on what Washington said was an Iranian drone operation threatening U.S. forces and commercial shipping in the Strait of Hormuz.
Iran confirmed the U.S. attack and said it had targeted a U.S. air base at 4:50 a.m.(0120 GMT) after what it described as an early morning U.S. strike near Bandar Abbas airport. It did not say where the base was.
Kuwait, which is home to a U.S. air base, did not say the threats were Iranian.
Gulf countries, including Kuwait, saw missile and drone attacks during the U.S.-Israel war on Iran. Hostilities have largely eased since a ceasefire came into effect in April, though drones have since been launched from Iraq towards Gulf countries, including Saudi Arabia and Kuwait.
