Iran fired two intermediate-range ballistic missiles at Diego Garcia but did not hit the U.S.-U.K. military base in the Indian Ocean, the Wall Street Journal reported, citing multiple U.S. officials.
One of the missiles failed in flight, while a U.S. warship fired an SM-3 interceptor at the other, although it could not be determined if the interception succeeded, the newspaper said on Friday. The Journal did not specify when the missiles were fired.
A spokesperson for the U.K. Ministry of Defence told CNBC it was preparing a statement.
The White House and the British embassy in Washington did not immediately respond to Reuters’ requests for comment.
The reported attack marked Iran’s first operational use of intermediate-range ballistic missiles and a significant attempt to reach far beyond the Middle East and threaten U.S. interests, the Wall Street Journal said.
The U.K. agreed in May 2025 to hand sovereignty of the Chagos Islands, where the Diego Garcia base is located, to Mauritius, which has long-disputed the U.K.’s acquisition and ownership of the archipelago in the Indian Ocean.
U.S. President Donald Trump has repeatedly criticized the U.K.’s plan.
