Iran launched two ballistic missiles toward the joint US-UK military facility at Diego Garcia on March 20, 2026, according to a Wall Street Journal report citing American officials. While neither missile struck the remote Indian Ocean base located 4,000 km from Iranian territory, the incident reveals Tehran's apparent advancement in long-range missile capabilities.
The attempted strike comes days after Iran warned UK Prime Minister Keir Starmer about "putting British lives at risk" by permitting US military operations from UK-administered bases. Diego Garcia has served as a critical hub for American bomber deployments to Asia since the Afghanistan and Iraq campaigns.
US defense sources disclosed one missile malfunctioned mid-flight, while a second was intercepted by a naval warship-based defense system. Neither Washington nor London has officially commented on the incident as of March 21.
Analysts note this marks Iran's first demonstrated capacity to target strategic Western assets in the eastern Indian Ocean. The Chagos Archipelago base remains central to monitoring Middle Eastern security developments and maintaining Asia-Pacific military readiness.
