The U.S. ambassador to Iraq says the United States may cut funding for Iraq's police because of their failure to punish those responsible for torture.

Zalmay Khalilzad said in an interview with The New York Times newspaper that U.S. officials are reviewing some programs because of a U.S. law that bans funding security forces that violate human rights.

But Khalilzad says he hopes Iraqi Interior Minister Jawad al-Bolani does punish those responsible to keep the funding.

Earlier this month, a special United Nations investigator said torture in Iraq may be worse now than it was when Saddam Hussein was in power. He called the situation out of hand and said he examined reports of torture at official Iraqi detention centers and by private militias.
