Iran expects understanding on nuke program by Friday

Iran's foreign minister says he believes it's possible to reach "an understanding or an agreement" with six world powers on his country's nuclear program before talks wrap up on Friday.

Mohammad Javad Zarif told CNN's Christiane Amanpour that he hopes both sides can sit down by Friday morning to prepare "some sort of a joint statement." Zarif refused to provide any details except to say "there won't be a suspension of our enrichment program in its entirety." (AP)
