Vienna: US Secretary of State John Kerry Friday praised a "genuine effort" by all sides negotiating a nuclear accord with Iran to get the deal done as a new deadline looms.
"We have some tough issues, but there`s been a genuine effort by everybody to be serious about this and to understand the time constraints that we`re working under. So we will continue to work. Tonight. Tomorrow. Sunday. And we certainly both want to try to see if we can arrive at a conclusion," Kerry said as he began a new round of talks with his Iranian counterpart Mohammad Javad Zarif.
