The latest round of nuclear talks held on three levels among representatives of Iran, the United States and the European Union have ended in Lausanne.

The negotiations on Thursday were held between Iran’s Foreign Minister Mohammad Javad Zarif and US Secretary of State John Kerry on the ministerial level.

Abbas Araqchi and Majid Takht-e Ravanchi, the Iranian deputy foreign ministers, also ended talks on a deputy level with US Under Secretary of State for Political Affairs Wendy Sherman and the EU deputy foreign policy chief, Helga Schmid.

Head of the Atomic Energy Organization of Iran Ali Akbar Salehi and US Secretary of Energy Ernest Moniz also ended their separate meeting in the Swiss city.

Zarif and his negotiating team had continued their intense marathon talks with the American side in Lausanne the previous week when the top Iranian diplomat also took some time to meet one-on-one in the Belgian capital of Brussels with the European foreign ministers of the P5+1 group - Frank-Walter Steinmeier of Germany, Philip Hammond of Britain and France’s Laurent Fabius. Zarif also sat down with EU foreign policy chief, Federica Mogherini, in Brussels.

Iran and the five permanent members of the UN Security Council - the United States, France, Britain, Russia, China and Germany - have been in talks to resolve outstanding issues surrounding the Islamic Republic’s peaceful nuclear program.
