Defense contractor KBR may have exposed as many as 100,000 people, including US soldiers, to cancer-causing toxins by burning waste in open-air pits in Iraq, says a series of class-action lawsuits filed against the company.

At least 22 separate lawsuits claiming KBR poisoned American soldiers in Iraq have been combined into a single massive lawsuit that says KBR, which until not long ago was a subsidiary of Halliburton, sought to save money by disposing of toxic waste and incinerating numerous potentially harmful substances in open-air “burn pits.”
