US and Iran speed up nuclear talks

A month from a nuclear deal deadline, the top US and Iranian diplomats gathered in Geneva today in an effort to bridge differences over how quickly to ease economic sanctions on Tehran and how significantly the Iranians must open up military facilities to international inspections.

The talks between US secretary of state John Kerry and Iranian foreign minister Mohammad Javad Zarif were likely to extend into Sunday, a negotiating round that officials described as the most substantive since world powers and Iran clinched a framework pact in April.
