Nuclear talks between Iran and leading world powers will resume on April 21 at the deputy level, Iranian Foreign Minister Mohammad Javad Zarif said day during a visit to Madrid.
Iran and the P5+1 group - the United States, Britain, France, Germany, Russia and China - reached a preliminary deal on Iran's disputed nuclear programme earlier this month and are aiming to reach a final deal by the end of June.
"My colleagues, with the deputy to (European Union foreign policy chief) Federica Mogherini and other political directors from the E3+3 will get together next Tuesday to start drafting," Zarif said.
"That's a difficult exercise, particularly with all the lawyers involved in the process and looking at the nitty-gritty of every word that is written down," Zarif said.
