Tehran Missile Attempt on Diego Garcia

In March 2026, Iran (Tehran) launched two ballistic missiles targeting the joint US–UK military base at Diego Garcia in the Indian Ocean. However, the attack was unsuccessful, as one missile was intercepted while the other failed mid-flight.

This marked one of Iran’s longest-range missile attempts (~4,000 km), indicating a significant expansion in its missile capabilities.
