Three Iraqis wounded in twin bombings in Baghdad

Rumsfeld linked success in Iraq to containing Iran amid concern over its nuclear ambitions.

"It seems to me that we need to put Iraq and Afghanistan in that context so that those people in our country who are deeply concerned about Iran, which is understandable, recognize that success in Afghanistan and success in Iraq is critical to containing the extreme impulses that we see emanating from Iran," Rumsfeld said.
