Kerry: Many technical differences have been solved

While the new round of talks between Iran and the US is underway in the Swiss city of Lausanne, the US Secretary of State says many technical differences over Iran's nuclear program have been solved.

John Kerry made the remarks in an interview with the CBS adding “By and large, most of the differences now are political decisions that need to be made in order to fulfill the promise of proving to the world that a program is peaceful.”

The interview was conducted Saturday in Egypt, where Kerry was attending a regional economic conference.

Kerry added that Tehran, “To its credit, has thus far lived up to every part of the agreement we made over a year ago,” referring to an interim agreement that has stalled parts of Iran’s nuclear program.

Iran and the P5+1 group, the US, Britain, Russia, France, China plus Germany clinched the interim deal in November 2013 over Tehran's nuclear work in the Swiss city of Geneva. 

Iran’s Foreign Minister Mohammad Javad Zarif and US Secretary of State John Kerry have begun a fresh round of talks over Tehran’s nuclear program in an attempt to bridge their differences on the outstanding issues surrounding Tehran's nuclear program. 

Zarif and Kerry opened the negotiations in the Swiss city of Lausanne on Monday.

Iran and the P5+1 countries are seeking to seal a comprehensive nuclear deal by July 1.The two sides have already missed two self-imposed deadlines for inking a final agreement since they signed the Geneva deal.
