Blackwater faces terrorism charges

"The shots fired on the Iraqis were unjustifiable," he said. "It was harsh and horrible. "

Iraqi investigators have said that they have a videotape showing that Blackwater guards opened fire against civilians without provocation.

The shooting happened while the contractors were escorting a US embassy convoy through Baghdad and eleven people were killed in the incident.

Meanwhile, a newspaper in North Carolina has reported US federal officials are investigating claims made by two former employees of the firm who pleaded guilty to weapons charges. The men are said to be cooperating with investigators as part of a plea bargain. According to the report, the firm was involved in the smuggling of automatic weapons into Iraq but the under-fire security contractor has denied the media reports. Press TV
