The allegation is that KBR/Halliburton knowingly exposed soldiers to toxins that might be killing them. The Iraq and Afghanistan Veterans of America have the news here and it ain't pretty.

This week reports surfaced that KBR, a military-contracting firm, may have knowingly exposed troops to dangerous toxins in Iraq.

In April of 2003, members of the Indiana National Guard were protecting KBR employees at a power plant in southern Iraq. After their service, some of these troops exhibited signs of cancer, tumors and rashes, and new reports indicate that these injuries may be the result of exposure to toxins present at the site.

Incredibly, CBS News has uncovered evidence that KBR may have known about the risks months before it took any action to inform those soldiers.

So far KBR has denied any wrongdoing, despite the evidence.

At least one Indiana Guardsman has died from lung cancer already. Others are sick. In fact, records from the CBS investigation show that 60 percent of the soldiers exposed "exhibit symptoms of exposure."
