The United States carried out 'self-defence strikes' on Iranian radar and drone-control facilities in response to the reported downing of a US MQ-1 drone over international waters.
According to the US central command (CENTCOM), Iranian air defence units shot down the drone, which was operating over international waters.
US fighter aircraft responded by destroying Iranian air defence systems, a ground-control station, and two one-way attack drones.
A telecommunications tower on Sirik Island in Iran was also reportedly attacked.
No American service members were harmed in the operation.
The US and Iran have exchanged occasional strikes since a ceasefire came into force in early April, while talks aimed at securing a longer-term agreement still continue.
