Iran Fires Missiles at Joint US-UK Diego Garcia Base 4,000km Away; Tehran Claims 'Israeli False Flag'

Two intermediate-range ballistic missiles were fired toward the joint US-UK Diego Garcia military base in the Indian Ocean, with the UK Defence Secretary confirming both failed to reach their targets. Iran's Foreign Ministry dismissed the allegations as an 'Israeli false flag' and 'disinformation,' while NATO Secretary-General Rutte stated the alliance 'cannot confirm' Israeli claims about the missile type. The attack demonstrates Iranian capabilities at double the 2,000km range Tehran has officially claimed, potentially putting Western European capitals within reach. The strike followed by hours the UK's announcement it would authorize US use of British bases for Hormuz operations.

Analysis
Diego Garcia strike follows Iran's March 4 IRGC claims of Hormuz control and tanker targeting. The 4,000km range demonstration, if confirmed Iranian, invalidates NATO's prior threat calculus based on Tehran's stated 2,000km missile ceiling.
