Iran Warns UK Against Military Cooperation With US in Any Strikes on Tehran

Tehran, Aug 2026 : Iranian Foreign Minister Seyed Abbas Araghchi has warned Britain against providing military assistance to the United States for any strikes against Iran, saying Tehran would consider cooperation with “aggressors” unacceptable regardless of existing defence arrangements.

Araghchi conveyed the warning during a telephone conversation with British Foreign Secretary Ed Miliband, according to a statement issued by Iran’s Foreign Ministry on Saturday. He said any British involvement in military operations against Iran, including allowing its territory or military facilities to be used for such attacks, would have serious consequences.

The Iranian minister criticised what he described as the British government’s “unjustified and inappropriate” policies towards Tehran. He specifically referred to London’s recent designation of Iran’s Islamic Revolutionary Guard Corps (IRGC) as a national security threat and accused Britain of being complicit in conflicts involving the United States and Israel.

Araghchi urged London to reconsider its position and warned that permitting British territory or facilities to be used for attacks against Iran could amount to an act of aggression under international law.

He argued that under international legal principles and the Convention for the Definition of Aggression, allowing the territory or facilities of one country to facilitate an unlawful military attack against another could give the targeted country the right to exercise self-defence.

The Iranian foreign minister also claimed that Tehran had entered diplomatic negotiations with Washington in good faith and had signed a memorandum of understanding with the United States in June aimed at ending the conflict. However, he alleged that Washington subsequently failed to honour its commitments.

Araghchi further discussed the sensitive situation surrounding the Strait of Hormuz, one of the world’s most strategically important maritime routes. He said Iran was working with Oman to establish operational mechanisms for managing shipping traffic through the waterway.

He warned that interference by third countries could complicate efforts to maintain safe and orderly maritime traffic in the region.

Miliband, for his part, maintained that Britain was not involved in the war against Iran and reiterated London’s position that diplomatic engagement remained the preferred means of resolving disputes.

The exchange comes amid heightened tensions between Iran and Western powers following a series of military confrontations in the region.

Last month, British Prime Minister Andy Burnham approved the continued use of British military bases by the United States for operations linked to Iran, maintaining an arrangement established under his predecessor. The decision has heightened concerns in Tehran over the potential role of British facilities in future US military operations.

The latest warning from Araghchi reflects Iran’s broader effort to deter Western countries from providing logistical or military support to US operations while keeping diplomatic channels open.

The tensions intensified after the United States and Israel launched joint attacks on Tehran and other Iranian cities on February 28. The strikes reportedly killed Iran’s then-Supreme Leader Ali Khamenei, senior military commanders and civilians.

Iran responded with waves of missile and drone attacks targeting US and Israeli military assets across the region and subsequently tightened its control over shipping activity in the Strait of Hormuz.

Against this backdrop, Tehran’s warning to London signals that any British military support to Washington could become a major point of confrontation as Iran seeks to balance military deterrence with diplomatic engagement.
