Iranian officials have officially rejected reports that the Islamic Republic launched ballistic missiles at the joint U.S.-U.K. military base on Diego Garcia, dismissing the claims as a dangerous fabrication.
In a formal statement on Sunday,22 March 2026, a senior Iranian official told Al Jazeera that Tehran was not behind the attempted strike, emphasising that such an operation is a physical impossibility for its current arsenal.
The denial follows reports from the Wall Street Journal on Friday alleging that two intermediate-range ballistic missiles (IRBMs) were fired toward the strategic Indian Ocean hub.
The “2,000 km” technical impossibility
Tehran's primary defence is rooted in the known technical specifications of its missile program. Foreign Minister Abbas Araghchi recently reiterated that Iran has strictly capped the range of its ballistic missiles at 2,000 kilometres (1,243 miles).
Diego Garcia is located approximately 4,000 kilometres (2,485 miles) from the southern coast of Iran – effectively double the reach of Tehran's most advanced systems like the Khorramshahr-4 or Sejjil-2.
Iranian officials argue that to hit Diego Garcia, they would need Intercontinental Ballistic Missiles (ICBMs), a class of weapon they maintain they do not possess. They describe the reports as “logistically and technically inconsistent” with their defensive doctrine.
Accusations of an Israeli “False Flag”
A significant counter-accusation has emerged from regional analysts and state-affiliated commentators in Tehran. They allege the missiles were actually launched by Israeli Dolphin-class submarines operating in the Indian Ocean, staged to look like an Iranian attack.
- Dragging Europe Into War: Skeptics argue that by “proving” Iran can hit a target 4,000 km away, Israel aims to demonstrate that major European capitals – such as Berlin, Paris, and London – are now within Iran's strike zone.
- The Strategic Goal: The theory suggests this is a calculated move to force European nations, who have been hesitant to join the full-scale conflict, into a direct military alliance against Iran.
- Submarine Capabilities: Israel's Dolphin-II submarines are known to carry advanced cruise missiles and are capable of long-range deployments in the Indian Ocean. Critics point out that a submarine launch could easily mask the true of origin of a flight path to frame a distant adversary.
Disputed capabilities: A shift in the balance
While Tehran denies the launch, Western intelligence agencies and the IDF have used the incident to claim that Iran's “secret” capabilities have finally been exposed.
“The Iranian regime has long lied about its range limits,” stated an IDF spokesperson on X. “Firing 4,000 km away proves they are no longer just a regional threat, but a global one.”
Regional fallout
The incident marks a dramatic escalation in Operation Epic Fury, the ongoing U.S.-led military campaign. If the international community accepts the 4,000 km range as fact, it fundamentally alters the security calculus for NATO, potentially ending European neutrality in the three-week-old war.
