The Interior Ministry said Monday that it was pulling the license of an American security firm allegedly involved in the fatal shooting of civilians during an attack on a U.S. State Department motorcade in Baghdad. The ministry said it would prosecute any foreign contractors found to have used excessive force in the Sunday incident, the Associated Press reported. Interior Ministry spokesman Abdul-Karim Khalaf said eight people were killed and 13 were wounded when security contractors working for Blackwater USA opened fire in a predominantly Sunni neighborhood of western Baghdad. «We have canceled the license of Blackwater and prevented them from working all over Iraqi territory. We will also refer those involved to Iraqi judicial authorities,» Khalaf said. The spokesman said witness reports pointed to Blackwater involvement but said the incident was still under investigation. It was not immediately clear if the measure against Blackwater was intended to be temporary or permanent.
