The European Commission says negotiators from the EU and Iran will resume talks on a deal to control Tehran's nuclear program on May 12 in Austria, and that they would be joined by officials from six world powers three days later.
The commission said in a statement that EU Political Director Helga Schmid and Iranian deputy negotiators Abbas Araghchi and Madjid Takht Ravanchi will resume their work on May 12 in Vienna.
Officials from the P5+1 group of world powers -- the United States, Russia, China, France, Britain, and Germany -- will join the talks on May 15.
The statement said negotiators will continue their work on the drafting of the main text of a framework agreement reached on April 2 in Switzerland after months of talks.
The two sides are aiming to complete a deal before a self-imposed deadline of June 30.
Iran has long insisted its nuclear program is only for peaceful purposes, mainly to produce energy.
