Intensive talks among senior negotiating officials over a comprehensive deal on Iran's nuclear energy program continue in the Austrian capital Vienna, PressTV reported.
On Monday, Iran's Foreign Minister Mohammad Javad Zarif, US Secretary of State John Kerry and EU foreign policy chief Catherine Ashton met in Vienna, where representatives from Iran and the five permanent members of the UN Security Council - Russia, China, France, Britain and the US - plus Germany are holding negotiations aimed at drawing up the draft text of a comprehensive agreement over Tehran's nuclear energy program.
The White House says Kerry will report the trend of the talks back to Washington for the decision on whether to extend a July 20 deadline for reaching the deal.
On Sunday, Zarif and Kerry also held a two-hour meeting. The top US diplomat was accompanied by US Deputy Secretary of State William Burns and Under-Secretary of State for Political Affairs Wendy Sherman, who is the country's representative in the nuclear talks.
On Sunday, Zarif also held separate talks with German Foreign Minister Frank-Walter Steinmeier, British Foreign Secretary William Hague, French Foreign Minister Laurent Fabius and Chinese Deputy Foreign Minister Li Baodong.
Iran and the six countries kicked off their sixth round of talks this year in Vienna on July 3.
The two sides sealed an interim deal in Geneva, Switzerland, on November 23, 2013. The deal came into force in January and expires on July 20, but can be extended depending on the agreement of all parties involved.
