BBC: The US is preparing to designate Iran's Revolutionary Guards force as a foreign terrorist unit, officials say.
If confirmed, this will be the first time official armed units of a sovereign state are included in the list of banned terrorist groups.
The classification would allow the US to target the force's finances.
The US has repeatedly accused Iran of destabilising Iraq and Afghanistan, blaming the Revolutionary Guards for supplying and training insurgents.
There are currently 42 organisations on the state department's list of foreign terrorist organisations.
They include al-Qaeda, the Lebanese militant group Hezbollah and the Palestinian groups Hamas and Islamic Jihad. Iran Guards ‘join US terror list’ (more)
