Iran has launched two ballistic missiles targeting the joint U.S.-U.K. military base on Diego Garcia in the Indian Ocean, according to a Wall Street Journal report citing U.S. officials on March 20. Neither missile hit its target, and one failed during flight. The other was reportedly intercepted by a missile defense system from a U.S. warship, though it remains unclear whether the interception was successful. The Pentagon has declined to comment on the incident.

The base, located about 4,000 kilometers from Iranian territory, is a key hub for U.S. operations in Asia and was previously used during air campaigns in Afghanistan and Iraq. Analysts cited by Al Jazeera said the launch demonstrates Iran’s possession of longer-range missiles than previously known, potentially exceeding 4,000 kilometers. This development could alter U.S. strategic calculations and raise concerns in London and the European Union.

The report also notes that Britain retains the lease of Diego Garcia despite agreeing to transfer the Chagos Islands to Mauritius, a decision criticized by former U.S. President Donald Trump.
