Tehran said on Wednesday that the exact timetable and venue of the next round of nuclear talks between Iran and Group 5+1 have not been set yet.

Foreign Ministry spokeswoman Marziyeh Afkham the remarks while addressing domestic and foreign reporters at her weekly press briefing.

However, she stressed that the talks will ˈdefinitelyˈ continue, IRNA news agency reported.

The last round of talks between Iran and the world six big powers (US, Britain, France, Russia and China plus Germany), known as the Vienna 6 talks, was held in Austria July 2-20 focusing on drafting a comprehensive agreement between the two sides.

During the talks, the two parties were to meet a six-month deadline (ended on July 20) for a deal to end the decade-old dispute.

Failing to reach a final comprehensive agreement until July 20, Iran and six world powers agreed to a four-month extension of negotiations on a long-term nuclear deal.
