A fragile ceasefire in the region collapsed early this morning as Iran and the United States exchanged direct military strikes, each accusing the other of initiating the escalation. The exchanges mark the most serious breach of the truce brokered six weeks ago, raising fears of a broader conflagration.
British diplomats at the Foreign Office in London have entered emergency consultations, according to sources. A senior official described the situation as "gravely concerning" and confirmed that the UK’s ambassador to Tehran and the charge d’affaires in Washington have been instructed to demand immediate de-escalation from both sides.
The strikes began at approximately 0230 local time when Iranian drones and missiles targeted two US military installations in Iraq, the Pentagon confirmed. In response, US air forces struck three Islamic Revolutionary Guard Corps facilities in southwestern Iran, including a command centre and a logistics depot. Casualty figures remain unconfirmed, though independent monitors report at least 19 injured on both sides.
Iran’s foreign ministry issued a statement accusing the United States of violating the ceasefire by conducting a covert operation inside Iranian territory last week. “The ceasefire was broken by Washington’s acts of aggression. Iran exercised its inherent right to self-defence,” the statement read. The US State Department countered, asserting that Iran had launched a series of small-scale attacks over the preceding 72 hours, culminating in tonight’s broader assault.
The ceasefire, which came into effect on 15 March, had reduced hostilities by 60 per cent according to UN figures. Its collapse threatens to undo weeks of European-led diplomacy, including a flurry of shuttle talks in Geneva last month.
The United Nations Security Council has scheduled an emergency closed-door session for later today. The UK, as a permanent member, is expected to call for an immediate cessation of hostilities and the resumption of talks. The British government has also activated its crisis response mechanism, with the Foreign Office advising against all travel to both countries.
Analysts note that the breakdown raises the stakes for the UK’s dual role as a US ally and a proponent of European diplomacy. A former British ambassador to Tehran said: “London must demonstrate that it can hold both sides accountable without being seen as taking Washington’s part. Its credibility as a mediator is on the line.”
The development comes amid rising domestic political pressure on the government to prioritise stability in the region, given its implications for oil prices and migration flows. The prime minister is expected to issue a brief statement within hours.
Both Iran and the United States have placed their respective armed forces on higher alert. The UK has not announced any change to its military posture but has urged its citizens in the region to leave immediately.
