US army using slaves in Iraq?

According to these articles from the Indo-Asian News Service and the Associated Press, the US army has been "buying" Indian workers who were told they were going to work in Kuwait:

"There were some 20 Indians in the bus. Once we knew that we were inside Iraq, we protested," Faisal said. "But the Americans told us that they had paid a Kuwait agency $1,000 (U.S.) for each man and therefore it was a must that we work for them."

This is an old story (from May '04), but I don't remember ever hearing about it before. Words fail me, here. Anything I can think of to say seems like it should go without saying, and only serves to belittle the magnitude of this atrocity.
