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 US strikes earlier on Thursday on ​what Washington said was an Iranian drone operation threatening US forces and commercial shipping in the Strait of ​Hormuz.

Iran confirmed the US attack and said it ​had targeted a US air base at 4:50am after ‌what ⁠it described as an early morning US strike near Bandar Abbas airport. It did not say where the base was.

Kuwait, which is home ​to a ​US air ⁠base, did not say the threats were Iranian.

Gulf countries, including Kuwait, saw ​missile and drone attacks during the ​US-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.
