The talks, aimed at reaching an enduring agreement to dismantle parts of Iran's nuclear infrastructure, are pushing against a new deadline, but a senior Iranian diplomat told RIA Novosti earlier Tehran does not see March 24 as the last day for the ongoing round of talks.
"Formally, the first deadline expires on March 24, but parties have agreed that the end of March is the actual deadline," the source said, adding that documents mention both dates.
A week of nuclear talks between Iran and the P5+1 group of international mediators – France, Britain, Russia, China, the United States and Germany – wrapped up in the Swiss city of Lausanne on March 20. Iran's Deputy Foreign Minister Abbas Arachi told RIA Novosti the next round of talks will take place on March 25.
