Authorities said some of the protesters begain painting the signs to Blackwater in red paint and they also blocked the road. They were arrested when they refused to disperse, authorities said.

Blackwater guards are accused of killing 17 Iraqis in Baghdad during a September 16 attack.

Families of those killed have sued Blackwater, charging that the Moyock, North Carolina-based firm violated U.S. law and fostered a culture of lawlessness among its employees.
