NAJAF, Iraq (Reuters) - A group of Iraq's Shi'ite militia groups said on Saturday that they strongly rejected the designation of Iran's Islamic Revolutionary Guards Corp (IRGC) as a terrorist organization by the United States.
Iran is responsible for the deaths of more than 600 U.S. service members in Iraq from 2003 until 2011, according to a Pentagon report provided to the State Department.
"During Operation Iraqi Freedom, DoD assessed that at least 603 U.S. personnel deaths in Iraq were the result of Iran-backed militants," Pentagon spokesman Navy Cmdr. Sean Robertson told Task & Purpose.
"These casualties were the result of explosively formed penetrators, other improvised explosive devices, improvised rocket-assisted munitions, rockets, mortars, rocket-propelled grenades, small-arms, sniper, and other attacks in Iraq."
Nearly 15 years after the U.S. military toppled Iraqi president Saddam Hussein, the U.S. government is replaying its post-invasion script that only a few isolated groups of fighters remain in Iraq. After two suicide bombers killed more than 30 people in Baghdad on Jan. 15, a U.S. commander in Iraq said it is too early to determine whether ISIS has morphed into an insurgency.
