"On April 22, 2009, the Secretary of State designated Revolutionary Struggle (RS) as a Foreign Terrorist Organization (FTO) under Section 219 of the Immigration and Nationality Act, as amended (INA). RS is a Greek terrorist organization responsible for numerous terrorist acts against Greek, U.S., and other targets since 2003, including the 2007 RPG attack on the U.S. Embassy in Athens, Greece and the March 9, 2009 detonation of a bomb outside a Citibank branch in Athens. Secretary Clinton took this action in consultation with the Attorney General and the Secretary of the Treasury. Also on April 22, 2009, the Secretary revoked the FTO designation of the Revolutionary Nuclei (RN) after completing the five year review of the FTO designation required by Section 219 of the INA. The Secretary concluded that the circumstances that were the basis for the prior designation of RN as an FTO have changed in such a manner to warrant revocation of the FTO designation. The Secretary has maintained the FTO designation of Revolutionary Organization 17 November (17N) after completing the five year review of the FTO designation required by Section 219 of the INA."
