Iran and world powers are to hold a fresh round of nuclear talks in Vienna on April 22-23, AFP has reported.
The talks will focus on continuing to build on the framework accord reached on Iran's nuclear programme with both sides working towards "a comprehensive solution to the Iranian nuclear issue based on the key understandings reached in Switzerland on April 2," according to an EU statement.
Next week's talks will include Helga Schmid of the EU's external affairs arm and Iranian Deputy Foreign Minister Abbas Araghchi.
Officials from the five U.N. Security Council members - Britain, China, France, Russia and the United States plus Germany - will also be present.
Last month's talks were extended but resulted in Iran accepting strict controls over its nuclear programme in return for the easing of some economic sanctions.
June 30 has been set as the deadline to reach an agreement.
