Kerry stresses unity over Iran nuclear deal

LONDON: US Secretary of State John Kerry on Saturday said he was "united" with Britain, France and Germany on seeking a nuclear deal with Iran, whose president said an agreement was "possible".

Kerry began talks in London with British Foreign Secretary Philip Hammond, France´s Laurent Fabius, Germany´s Frank-Walter Steinmeier and EU foreign affairs chief Federica Mogherini, amid reports of disagreements over their negotiating position.

The gathering comes one day after the latest round of talks between Iran and the P5+1 group of world powers -- Britain, China, France, Russia and the United States plus Germany -- ended with no breakthrough.

Both Washington and Tehran indicated, however, that major steps had been made towards a deal that would see Iran scale back its controversial nuclear programme in return for relief from sanctions.

Kerry, speaking in Lausanne in Switzerland before heading to London, said there had been "substantial progress".

Iran´s President Hassan Rouhani declared separately that "an agreement is possible".

"There is nothing that cannot be resolved," the official IRNA news agency quoted him as saying.

But he conceded there were still "points of disagreement".
