Iranian Supreme Leader Ali Khamenei has expressed doubts about the success of talks on Tehran's nuclear program, RIA Novosti reports.
Vienna will host a new round of talks between Iran and six mediators of the nuclear program (Russia, US, China, UK, France, Germany) tomorrow. The talks will continue until February 20. A delegation headed by Iranian Foreign Minister Mohammad Javad Zarif has arrived in Vienna.
Iran agreed to freeze the program in exchange for ease of sanctions at a meeting with the six mediators in November. Realization of the agreement reached then started on January 20.
