Four Iraqi men are suing US military contractors who they say tortured them while they were detained in Abu Ghraib prison. The companies named in the lawsuit are CACI and L-3 Services, as well three individual contractors. One of the plaintiffs, an Iraqi farmer, said he was caged, beaten, threatened with dogs, and given electric shocks during more than four years in US detention. The Iraqi farmer was released in March without being charged and without any judicial process.
