US says Iran's suspension of cooperation with IAEA 'unacceptable'

Iran's suspension of cooperation with the International Atomic Energy Agency (IAEA) is unacceptable, says US State Department spokeswoman Tammy Bruce. "We'll use the word unacceptable, that Iran chose to suspend cooperation with the IAEA at a time when it has a window of opportunity to reverse course and choose a path of peace and prosperity," Bruce tells a briefing in Washington.
