Iran Charges war crimes in Iraq

You, who have used nuclear weapons against innocent people, who have used uranium ordnance in
Iraq, should be tried as war criminals in courts," Mahmoud Ahmadinejad said in an apparent reference to the United States.

Ahmadinejad did not elaborate, but he apparently was referring to the U.S. military's reported use of artillery shells packed with depleted uranium, which is far less radioactive than natural uranium and is left over from the process of enriching uranium for use as nuclear fuel.

Since the Iraq war started in 2003, American forces have fired at least 120 tons of shells packed with depleted uranium, an extremely dense material used by the U.S. and British militaries to penetrate tank armor. Once fired, the shells melt, vaporize and turn to dust.

"Who in the world are you to accuse Iran of suspicious nuclear armed activity?" Ahmadinejad

Note, Iraq had no tanks in this invasion, all tanks were taken out in Desert Storm before Iraq surrendered the first time.
I have read some reports that Children in Iraq are having much higher rates of cancer from exposure to the uranium but I have not confirmed the stories. Also read some reports that many of our vets got sick after Desert Storm.
120 Tons is a very big bunch of shells but the count above goes back to 2003.
