Green Party nominee Jill Stein claimed during a Wednesday night town hall that U.S. forces killed 1 million people during the Iraq War and occupation.

"Since 2001 we have killed a million people in Iraq alone, which is not winning us the hearts and minds in the Middle East," Stein told an audience member during the CNN town hall.

But the former physician's death toll estimate appears to contradict others.

The Iraq Body Count project estimates 119,00 Iraqis were killed from 2003 to 2013, with 112,000 to 123,000 of those deaths being civilians.

Another study by the Public Library of Sciences found 500,000 Iraqis died as a result of the U.S. invasion.

The only report that was comparable to Stein's statement was by the London-based Opinion Research Business company. They found an estimated 1.2 million deaths as a result of the conflict from 2003 to 2007.

Stein maintained the U.S. invasion of Iraq has caused "failed states, mass refugee migrations and repeated terrorist threats that get worse with each [presidential] cycle."

Stein supports following international law and non-interventionist policies.
