Iranian, US and EU negotiating teams led by Foreign Minister Mohammad Javad Zarif and US Secretary of State John Kerry and EU Foreign Policy chief Federico Mogherini began last-ditch negotiations to work out a comprehensive nuclear deal.

Iranian Foreign Minister Mohammad Javad Zarif said he believed there should be no further extension to the talks but he would negotiate as long as needed.

"I always believe there shouldn't be any extension but we could work as long as necessary to finish this," Zarif said as he met Wang.

In addition to the foreign ministers, the head of Atomic Energy Organization of Iran (AEOI) Ali-Akbar Salehi and US Secretary of Energy Ernest Moniz are present in the meeting.

Salehi asserted that the technical talks ended, noting that the text of the nuclear agreement is being proofread.

Deputies Foreign Minister Abbas Araqchi and Majid Takht-e Ravanchi, US Undersecretary of State Wendy Sherman and Deputy EU Foreign Policy chief Helga Schmid, who have held long meetings during the past several days also joined the meeting.
