Iran has attempted a direct strike on a key Western military installation, underlining just how far the conflict has escalated, and raising serious questions about Britain’s strategic posture.
US officials say Tehran fired two medium-range ballistic missiles at the joint UK-US base on Diego Garcia, in the Chagos Islands. Neither missile reached its target, with one reportedly intercepted by a US warship using an SM-3 system, while the other failed mid-flight, according to The Wall Street Journal.
This marks the first confirmed use by Iran of intermediate-range ballistic missiles at such distances, around 2,400 miles, signalling a significant shift in capability and intent. Reports differ slightly on timing, US media say the attack took place on Friday morning local time, while the BBC suggests it occurred sometime in the preceding days.
The missile believed to have been used is the Khorramshahr-4, a 20-tonne system capable of carrying up to 80 cluster munitions. With a lighter payload, analysts believe it could strike targets as far away as Diego Garcia, placing not just British overseas bases but potentially parts of Europe within range.
That stands in contrast to recent claims by Iran’s foreign minister, Abbas Araghchi, who said Tehran was limiting its missile range to 1,242 miles. The attempted strike appears to tell a different story.
Defence experts warn that if Iran can reach Diego Garcia, then RAF Akrotiri in Cyprus is even more exposed. That has led to growing concern about Britain’s preparedness and the vulnerability of its overseas assets.
Araghchi himself issued a warning, saying the UK had been “putting British lives at risk” by allowing US forces to operate from British bases. He told Foreign Secretary Yvette Cooper that such cooperation amounted to “participation in aggression” and that Iran had a right to self-defence.
The incident is likely to intensify pressure on the UK to take a more active role alongside the US in the Middle East. But it also highlights a deeper problem, whether Britain actually has the military capacity to do so.
Conservative leader Kemi Badenoch argued that Britain is being “dragged into” the conflict “whether we like it or not,” and criticised Prime Minister Keir Starmer for failing to support earlier US strikes.
Only recently, the Labour Government agreed to allow US forces to use British bases for strikes aimed at protecting shipping in the Strait of Hormuz, through which roughly 20 per cent of global oil passes. Previously, permission had been limited strictly to defensive operations.
Downing Street justified the shift as “collective self-defence.” But the attempted strike on Diego Garcia suggests that Iran is willing to retaliate directly against those bases.
Meanwhile, concerns about Britain’s readiness are mounting. Earlier this month, a suspected Hezbollah drone struck a hangar at RAF Akrotiri used by US U-2 spy planes. The Royal Navy dispatched HMS Dragon, a Type 45 destroyer capable of missile defence, but it has yet to reach Cyprus, last seen near Gibraltar, some 2,000 miles away.
Defence analyst Philip Ingram was blunt in his assessment. The delay, he said, makes “a laughing stock” of government assurances. He warned that Cyprus is clearly within range of Iranian ballistic missiles and criticised the failure to prioritise that threat.
“They’ve ignored the single biggest threat which is the potential ballistic missile threat. The attack on Diego Garcia has just highlighted that,” he said.
“It’s time that the Government woke up and realised that we have to take this seriously and put more assets into protecting your British citizens, British interests and everything else and with that, that means helping our allies in providing the defences that they need.”
British forces in the region have already faced repeated threats, often relying heavily on US systems for protection.
At the same time, messaging from Washington remains mixed. Donald Trump has said he is considering “winding down” the war, claiming the US is close to achieving its objectives. Yet reports suggest the Pentagon is also exploring options that could include deploying ground troops or seizing key Iranian infrastructure such as Kharg Island.
Against this backdrop, the situation has cast renewed scrutiny on Starmer’s controversial plan for the Chagos Islands. The proposal would see Britain transfer sovereignty to Mauritius while leasing back Diego Garcia at significant long-term cost to British taxpayers.
Critics argue this is strategic folly. Handing over territory that hosts one of the West’s most critical military bases, especially to a country seen as closer to China and Iran, while paying billions to lease it back, looks increasingly indefensible in light of recent events.
At a moment when Iran is demonstrating the ability to strike targets thousands of miles away, weakening Western strategic positioning in the Indian Ocean risks looking not just misguided, but reckless.
Put bluntly, it feeds a broader concern, that at a time of rising global threats, Britain’s leadership is moving in the opposite direction, undermining its own defences and, in effect, helping to disarm the West in a highly contested region.
Narendra Modi criticised the attempted strike of Iran on Diego Garcia. Modi, of course ! Who else than the “Ayatollah” of Hindutva who, together with his accomplice namely the Mauritius Govt, want Indian Ocean to be Hindu’s Ocean through MAHASGAR? It is India which worked and is still working behind the curtains for the Chagos surrender deal to be done.
Let it be clear, Mauritius Govt is not neutral and not an ally of China, Iran nor Russia despite State to State agreements on cooperation. Mauritius is a vassal country of India for ideological reasons, not the India of Nehru, rather the India of BJP’s Hindu supremacist and racist philosophy named Hindutva.
The people of the whole Indian Ocean knows that, the Americans and the French too. Except the British who still don’t have the slightest idea how evil these Hindutva people in Mauritius and India are. The deliberate non-consultation of the Chagossians on the treaty is one of their work.
