Iran Foreign Ministry spokesman, Saeed Khatibzadeh, said yesterday that the negotiations currently taking place in the Austrian capital, Vienna, between Tehran and the world powers over the 2015 nuclear deal have "achieved some progress".
"We are moving on the right track and some progress has been made, but we have not reached the final stage yet," Khatibzadeh told reporters.
"We are now at a stage where difficult issues should be negotiated. We are not in a hurry. We do not have any direct or indirect negotiations with the United States in Vienna," he added.
Last Tuesday, Vienna hosted talks aimed at reviving the nuclear deal between Iran and the world powers and bringing the United States back to the nuclear agreement.
In response, Tehran reduced its commitments under the deal and increased uranium enrichment to 20 per cent, exceeding the 3.67 per cent limit set by the deal.
