Najlaa International Catering Services, a subcontractor to KBR, an engineering, construction and services company, hired the men, who're from India, Nepal, Sri Lanka and Bangladesh. On Tuesday, they staged a march outside their compound to protest their living conditions.

"It's really dirty," a Sri Lankan man told McClatchy, speaking on the condition of anonymity because he still wants to work for Najlaa. "For all of us, there are about 12 toilets and about 10 bathrooms. The food — it's three half-liter (one pint) bottles of water a day. Bread, cheese and jam for breakfast. Lunch is a small piece of meat, potato and rice. Dinner is rice and dal, but it's not dal," he said, referring to the Indian lentil dish.

After McClatchy began asking questions about the men on Tuesday, the Kuwaiti contractor announced that it would return them to their home countries and pay them back salaries. Najlaa officials contended that they've cared for the men's basic needs while the company has tried to find them jobs in Iraq.

The lawsuit also accuses KBR of shipping ice in mortuary trucks that “still had traces of body fluids and putrefied remains in them when they were loaded with ice. This ice was served to U.S. forces.”

Eller also accuses KBR of failing to maintain a medical incinerator at Joint Base Balad, which has been confirmed by two surgeons in interviews with Military Times about the Balad burn pit. Instead, according to the lawsuit and the physicians, medical waste, such as needles, amputated body parts and bloody bandages were burned in the open-air pit.

“Wild dogs in the area raided the burn pit and carried off human remains,” the lawsuit states. “The wild dogs could be seen roaming the base with body parts in their mouths, to the great distress of the U.S. forces.”
