British Foreign Secretary William Hague said today that talks on Iran's nuclear programme in Geneva were making progress and that world powers needed to seize the chance for a historic deal.
"These negotiations have made very good progress and continue to make progress," Hague told journalists as crunch talks between six world powers and Iran stretched into a third day.
Hague said there were "still important issues to resolve" but that "momentum has built up" for an agreement.
"There is now a real concentration on these negotiations so we have to do everything we can to seize the moment and seize the opportunity to reach a deal that has eluded the world," he said.
He said it was still "certainly not possible" that a deal would be reached by today.
"It is too early to say that we will reach a successful conclusion today," he said.
"Any agreement is going to require some flexibility on all sides... (the deal) has to be one that the world has confidence in, that the world as a whole can have confidence in," Hague added.
