Iranian Foreign Minister Mohammad Javad Zarif said that parties engaged in nuclear talks had reached a breakthrough, hoping that the negotiating teams will start drafting the final deal on Wednesday.

“We’ve been working since 7:30 in the morning and it’s been a very long day for all delegations. We have accomplished quite bit, but people needed to get some rest and start over early in the morning,” he said in Lausanne, Switzerland, where the talks are underway, early on Wednesday.

"Drafting should, of course, start this morning," he said, adding that the seven nations will likely issue a joint statement at the end of their meeting today.

Iran and the P5+1 group -- Russia, China, France, Britain, the US and Germany -- which are holding talks in the Swiss city, had been supposed to reach a mutual understanding by late Tuesday as part of broader efforts to clinch a final agreement on Tehran nuclear activities by end of June.

A few minutes earlier, Russian Foreign Minister Sergei Lavrov said Iran and the world powers have eventually worked out an agreement, adding that the seven nations are now working on drafting the text.

Speaking Russian media at the end of marathon talks in Lausanne, Switzerland, early Wednesday morning, Lavrov said Iran and the G5+1 (the US, Britain, China, Russia and France plus Germany) have reached an agreement in principle on all key issues.
"Now this has to be drafted," he said.
