The video has sparked concern that private security companies, which are not subject to any form of regulation either in Britain or in Iraq, could be responsible for the deaths of hundreds of innocent Iraqis. The video...first appeared on a website that has been linked unofficially to Aegis Defence Services... Last night a spokesman for defence firm Aegis Defence Services...confirmed that the company was carrying out an internal investigation to see if any of their employees were involved... A spokesman for Aegis Defence Services, said: "There is nothing to indicate that these film clips are in any way connected to Aegis." [also refers to Sandline International]
