Iran's foreign ministry on Tuesday condemned Britain's decision to designate the Iranian Revolutionary Guard Corps as a security threat, calling the move "unjustified" and "irresponsible". The ministry said the IRGC was an official part of Iran's armed forces and accused Britain of violating international law by targeting a state institution, said Reuters. Britain on Monday banned support for the IRGC and a linked group under new powers aimed at preventing foreign states from using proxies for activities such as surveillance and sabotage. Iran, which is at war with the United States and Israel, has previously denied using proxies.
