US has 'fervent hope' of Iran nuclear deal in weeks, Secretary Kerry says

US Secretary of State John Kerry met on Friday with his Iranian counterpart Mohammad Javad Zarif and the EU's chief negotiator Catherine Ashton in a bid to narrow the gaps, Agence France Presse reports.

"It remains our fervent hope that Iran and the P5+1 can in the next weeks come to an agreement that would benefit the world," Secretary Kerry said at a UN meeting ahead of the trilateral talks.
