Tehran's state media have condemned the Obama administration for taking an Iranian militant group formerly allied with Saddam Hussein off the U.S. terrorism list, saying it shows Washington's "double standards."
State TV said the United States considered the Mujahedeen-e-Khalq as "good terrorists" because it used the group against Iran.
The comments Saturday came in reaction to the State Department's decision Friday. The delisting means any assets the MEK has in the United States are unblocked and Americans can do business with the organization.
The MEK helped Islamic clerics overthrow Iran's shah before carrying out a series of bombings and assassinations against the Iranian government and public targets. It fought in the 1980s alongside Saddam's forces in the Iran-Iraq war but disarmed after the U.S. invasion of Iraq in 2003.
