Iran has denied targeting a joint US-UK military base in the Indian Ocean, Al Jazeera reported, citing a senior Iranian official.

Located on the remote island of Diego Garcia in the Chagos Archipelago, the military site was reportedly targeted by two ballistic missiles early on Friday local time.

Neither of the alleged missiles hit the base, which hosts about 2,500 personnel, most of them American. Washington has described the installation as “an all but indispensable platform” for operations across the Middle East, South Asia, and East Africa.

British Foreign Secretary Yvette Cooper condemned the incident as “reckless Iranian threats,” while insisting that the UK would not take part in offensive operations and would limit its role to defensive support.

Iran has carried out retaliatory strikes against multiple US bases in the Middle East and launched drones toward the UK’s Akrotiri air base in southern Cyprus, reportedly causing minor damage to the facility.

Downing Street said on Friday that ministers had allowed the US to use UK bases to launch strikes on Iran. British Prime Minister Keir Starmer, however, has declined US President Donald Trump’s invitation to send warships to the Strait of Hormuz.

US President Donald Trump said Britain “should have acted a lot faster,” while Iranian Foreign Minister Abbas Araghchi accused Starmer of “putting British lives in danger.”
