All-night session for negotiators at Iran nuclear talks
Iran nuclear talks have adjourned after an all-night session and will resume in a few hours.
With even a vague outline of an Iran nuclear deal eluding their grasp, negotiators went into double overtime in a marathon attempt to find common ground for a more important task - forging a final deal by the end of June.
Iran and six world powers had cited progress in abandoning their March 31 deadline for the basic understanding that would prepare the ground for a new phase of negotiations on a substantive deal.
But as differences persisted into late last night, the US State Department announced that John Kerry was postponing his departure and would remain until at least this morning.
At around 6am local time today, in Lausanne, Switzerland, State Department spokeswoman Marie Harf tweeted that the talks had broken after an all-night session and would resume in a few hours.
The talks - the latest in more than a decade of diplomatic efforts to curb Iran's nuclear prowess - hit the week-long mark on today.
Diplomats from the five permanent members of the UN Security Council and Germany are scrambling to reach a framework accord with Iran.
