The UK Foreign Office has summoned Iran's charge d'affaires over the transfer of ballistic missiles to Russia.
It said the UK government "was clear in that any transfer of ballistic missiles to Russia would be seen as a dangerous escalation and would face a significant response".
Earlier, Iran's foreign minister Abbas Araghchi wrote on X that Tehran had not delivered any ballistic missiles to Russia and sanctions imposed on Iran by the US, Britain, Germany and France would not solve any problems between them.
