In a phone call with UK Foreign Secretary Ed Miliband, Iranian Foreign Minister Abbas Araghchi warned against any third-party intervention in the Strait of Hormuz.
In a statement on Saturday, Araghchi said Iran is working with Oman on legal and technical mechanisms to manage maritime traffic in the Strait of Hormuz. He stressed that any third-party intervention would weaken regional stability and further complicate the situation.
The Iranian minister sharply criticized the UK's recent stance, accusing London of being complicit in and engaging in US and Israeli attacks against Iran.
Araghchi also voiced concern over the UK's decision to designate Iran's armed forces as a threat to British national security, and called on London to review this policy.
Touching on the legal dimension of the conflict, Araghchi said that under international law, countries that allow their territory or facilities to be used for an attack against another state are considered to have participated in the act of aggression, and such situations give Iran the right to legitimate self-defence.
Regarding diplomatic efforts, Araghchi argued that Iran had previously taken constructive steps towards peace and that a final agreement to stop the war was reached in mid-June, but the US reneged on its commitments and prevented the deal from being implemented.
In response, UK Foreign Secretary Ed Miliband said the new British government was not seeking war and was not part of any military conflict against Iran. Miliband said London's primary goal is to continue diplomacy, reduce tensions and improve relations between the two countries.
