VIENNA, April 9 (UPI) -- The third round of Iranian nuclear talks concluded in Vienna, Austria on Wednesday.
Delegates from the P5+1 countries -- the five permanent members of the U.N. Security Council (Britain, China, France, Russia, the United States) plus Germany -- met with the Iranian delegation led by Foreign Minister Javad Zarif and European Union foreign policy chief Catherine Ashton on Tuesday and Wednesday to work toward a comprehensive Iranian nuclear agreement.
At the conclusion of their meetings, Ashton issued a joint statement with Zarif noting "we have now held substantive and detailed discussions covering all the issues which will need to be part of a Comprehensive Agreement."
The delegates will reconvene in Vienna on May 13 "to bridge the gaps in all the key areas and work on the concrete elements of a possible Comprehensive Agreement."
Both leaders acknowledged that "A lot of intensive work" remains in order "to overcome the differences which naturally still exist at this stage in the process."
The May meeting will mark the fourth meeting since the Joint Plan of Actions was implemented in January.
