U.S. likely to declare Iran's Guards Corps as terrorist organisation

The United States is expected to designate Iran's elite Revolutionary Guards Corps a foreign terrorist organization, three U.S. officials told Reuters, marking the first time that Washington will formally label another country's military a terrorist group.

The decision, which critics warn could open U.S. military and intelligence officials to similar actions by unfriendly governments abroad, is expected to be announced by the U.S. State Department, perhaps as early as Monday, the officials said. It has been rumored for years.
