UK Confirms Iran Fired Two IRBMs at Diego Garcia; Attack Reveals Missile Range Far Beyond Stated Limits

The UK confirmed on March 22 that Iran fired two intermediate-range ballistic missiles at Diego Garcia, the joint US-UK military base in the Indian Ocean roughly 4,000 km from Iran. One missile failed mid-flight; the other was intercepted by a US warship. Tehran denies responsibility. The strike revealed Iranian missile capabilities far exceeding previous assessments and contradicting Foreign Minister Araghchi's claim that Iran 'intentionally limited' its missiles to below 2,000 km range. Israel's military chief cited the attack as evidence that European capitals — Berlin, Paris, Rome — are now within Iranian missile range, fundamentally altering the strategic calculus for NATO allies.
