'No breakthrough yet' in Iran talks, Britain says

British Foreign Secretary Philip Hammond said Thursday there was no breakthrough yet in the Iran nuclear talks as they stretched into a sixth day, but insisted work was continuing to reach a deal.

"The work goes on. You are going to see ministers coming and going to maintain the momentum of these discussions. I don't think we're at any kind of breakthrough moment yet and we will do whatever we need to do to keep the momentum," Hammond said as he arrived in Vienna for talks with US Secretary of State John Kerry.
