Summary: Iraq has denied North Carolina-based Blackwater Worldwide, which guards American diplomats in Iraq, an operating license because of a deadly shooting spree in Baghdad. Iraqi officials said the lingering outrage over a September 2007 shooting in Baghdad’s Nisoor Square that left 17 Iraqi civilians dead led to its decision. The shooting strained relations between Washington and Baghdad and fueled the anti-American insurgency in Iraq, where many Iraqis saw the bloodshed as a demonstration of American brutality and arrogance.
