Iranian Foreign Minister Mohammad-Javad Zarif arrived in Vienna on Tuesday to continue nuclear talks with the world powers, state-run IRNA news agency reported.

Top nuclear negotiators of both sides are to resume talks in the Austrian capital today June 30th, the deadline for nuclear talks. Zarif is also scheduled to hold talks with his US counterpart John Kerry.

The Iranian diplomat left the Austrian capital late on Sunday, but his deputies Abbas Araqchi and Majid Takht-e Ravanchi stayed there to continue talks on writing the text of the comprehensive agreement.

In the absence of Zarif, the Iranian negotiators held four rounds of talks with European Union deputy foreign policy chief Helga Schmidt on Monday. The US Undersecretary of State Wendy Sherman was present in one round of those talks.

Iran, the European Union and representatives of the P5+1 have been holding intensive nuclear talks to reach a final agreement on Iran's nuclear issue.
