LONDON, ENGLAND: The United Kingdom condemned what it called Iran’s “reckless attacks” after ballistic missiles were launched toward the joint US-UK military base on Diego Garcia in the Indian Ocean.

Iran fired two intermediate-range ballistic missiles at the base on Friday morning local time. Neither missile struck the facility, the official said.

The semi-official Mehr news agency in Iran later confirmed that the missiles were aimed at what it called “the military base of the oppressors in Diego Garcia.”

Diego Garcia attack marks widening reach

The targeting of Diego Garcia is significant because of the island’s strategic military importance. Located around 3,800 kilometres from Iran, the base hosts an airfield capable of accommodating long-range US bombers.

Mehr described the strike as an important escalation, saying it represented “a significant step by the Islamic Republic of Iran in threatening the interests of the United States and its allies beyond the borders of West Asia.”

The attempted strike signaled an expansion of the conflict’s geographic scope, bringing a key Western military outpost in the Indian Ocean into Iran’s line of fire.

Britain calls attack a threat to its interests

Responding on Saturday, March 21, the UK Defence Ministry said Iran’s actions posed a direct challenge to British interests and its allies.

"Iran’s reckless attacks, lashing out across the region and holding hostage the Strait of Hormuz, are a threat to British interests and British allies,” the ministry said.

The statement points to London’s growing alarm over Tehran’s military moves and the broader threat they pose to regional stability and maritime security.

UK had authorized use of bases for defensive operations

The attack came a day after the British government announced that it had granted the United States permission to use British bases for specific defensive operations.

According to the UK government, the approval was given for operations intended “to degrade the missile sites and capabilities being used to attack ships.”

The disclosure highlights Britain’s direct support for US-led defensive measures in the region, even as tensions with Iran continue to intensify.

The reference by the UK Defence Ministry to the Strait of Hormuz points to wider Western concerns about the impact of the conflict on global shipping and energy supplies.

With Iran accused of escalating attacks across the region, the attempted strike on Diego Garcia is likely to deepen fears of a broader confrontation involving US and British military interests far beyond the Gulf.
