The White House says President Barack Obama and Secretary of State John Kerry met on July 16 to discuss the "path forward" on Iranian nuclear talks.
White House spokesman Josh Earnest says Iran's track record in implementing an interim agreement has been "surprisingly favorable." But he said there are still gaps between Iran and world powers as they work toward a final accord.
He would not confirm reports citing diplomats that said Iran and the five permanent UN Security Council members plus Germany have tentatively agreed to extend the talks beyond a July 20 deadline.
The interim agreement which was struck in November froze aspects of Iran's nuclear program in exchange for an easing of some sanctions. It expires on July 20.
