The decision, rumoured for years, is expected to be announced by the US State Department as early as Monday.
Iranian officials have cautioned the United States against pushing ahead with a rumoured move to designate Iran’s Islamic Revolutionary Guard Corps (IRGC) a “terrorist” group, warning it could destabilise the region and draw a tit-for-tat response.
The expected shift in Washington’s policy was initially reported by the Wall Street Journal on Friday, which cited unnamed US officials claiming it could be rolled out as soon as Monday.
Seen as part of a broader effort to make good on US President Donald Trump’s vow to take a tougher line against Iran, the proposal would – if implemented – mark an unprecedented step against an entire institution of a foreign government.
It would also go far beyond pre-existing sanctions put in place by the US to target entities linked to the IRGC, including the Quds Force, which is in charge of the force’s operations abroad.
On Sunday, Iran’s Foreign Minister Javad Zarif said such a measure was “another US disaster” in the making, and warned of the consequences it could have.
“#NetanyahuFirsters who have long agitated for FTO designation of the IRGC fully understand its consequences for US forces in the region,” Zarif wrote on Twitter, referring to supporters of Benjamin Netanyahu, the prime minister of Israel, Iran’s regional archenemy.
“In fact, they seek to drag US into a quagmire on his behalf. @realDonaldTrump should know better than to be conned into another US disaster,” Zarif added.

Separately, Mohammad Ali Jafari, the IRGC’s commander, said US troops stationed in the Middle East would “lose their current status of ease and serenity” should Washington went ahead with “such foolishness” and warned of a “reciprocal move” from Tehran.
“If reports prove to be true that the stupid US administration intends to designate the IRGC as a terrorist organisation, then the IRGC [Revolutionary Guards] will also specify the US army as a group like ISIL in all parts of the world, specially the Middle-East,” Jafari said, using the acronym for the Islamic State of Iraq and the Levant group, also known as ISIS.
Jafari’s remarks coincided with a statement issued by a majority of Iranian legislators confirming that the country’s parliament would respond-in-kind to any shift by Washington, according to a report by Iran’s state-run IRNA news agency.
Iran’s most powerful security organisation, the IRGC was set up to protect the country’s Shia clerical ruling system after its 1979 Islamic Revolution, which toppled the Western-allied secular monarch Shah Mohammad Reza Pahlavi and led to the formation of the Islamic Republic.
The force is in charge of Iran’s ballistic missiles and nuclear programmes, and answers directly to Supreme Leader Ayatollah Ali Khamenei. It is estimated to have 125,000 personnel, comprised of army, navy and air units.
After the 1980s’ Iran-Iraq war, the IRGC also became heavily involved in reconstruction and has expanded its economic interests to include a vast network of businesses, ranging from oil and gas projects to construction and telecommunication.
