"A meeting of the E3+3 [also known as P5+1] group will take place on September 22 on the ministerial level," the source said.
Last month, media reports indicated that the next Iran and P5+1 session would take place in September on the sidelines of the UN General Assembly with the purpose of going over some differences in opinion with regard to the implementation of the Iran deal.
On July 14, 2015, Iran the P5+1 group of countries, consisting of the United States, Russia, China, France and the United Kingdom plus Germany, reached the Joint Comprehensive Plan of Action (JCPOA) agreement to ensure the peaceful nature of Iran’s nuclear program in return for sanctions relief.
In mid-January, the International Atomic Energy Agency (IAEA) verified Tehran’s compliance with the agreement.
Iranian Foreign Minister Mohammad Javad Zarif said in August that Iran was planning to discuss US violations of the deal at the next meeting of the commission on the implementation of the agreement.
