TEHRAN (Tasnim) � Austria's capital of Vienna is scheduled to host a fresh round of talks over Tehran's nuclear energy program beginning Tuesday, with negotiators from Iran and world powers resuming work to draft the text of a comprehensive nuclear deal.

The upcoming talks in Vienna will run for four days and the sessions will mainly be devoted to consultations between Iranian deputy foreign ministers and the European Union's deputy secretary general for the external action service, Helga Maria Schmid.

The EU coordinates diplomacy with Iran on behalf of the Group 5+1 (Russia, China, the US, Britain, France and Germany).

Technical experts will also hold talks in Vienna during the four days.

Iran and the six powers are in talks to hammer out a lasting accord that would end more than a decade of impasse over Tehran's peaceful nuclear program.

On April 2, the two sides reached a framework nuclear agreement in Lausanne, Switzerland, with both sides committed to push for a final deal until the end of June.

Later on April 30, diplomats from Iran and the EU launched another round of nuclear talks in New York, on the sidelines of the 2015 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) to draft the long-awaited accord.

Iranian President Hassan Rouhani on Sunday said a great deal of mutual understanding has been developed in the nuclear talks, reiterating that a final agreement depends on whether the other side will show the necessary determination.
