Progress in nuclear talks - Kerry
"Substantial progress" has been made toward ensuring that Iran's nuclear program will not lead to weapons development, US Secretary of State John Kerry said.
But he added that important gaps still stand in the way of an agreement.
Speaking after a week of nuclear talks with Iran, Kerry said today that the US wasn't rushing for an agreement even as a March 31 deadline looms for a framework agreement.
He said fundamental decisions needed to be made and stressed that world powers and Iran have an opportunity right now for a diplomatic solution.
Kerry was leaving Switzerland later today for London to meet European allies, before returning to Washington.
Talks with Iran resume next week.
