Al Jazeera reporter in Tehran: The diplomatic way through mediators continues. In this context, there is an American proposal that wants to combine Iran's proposal, which includes seven conditions, with American nuclear demands, including the issue of enriched uranium and testing, and the implementation of the agreement should be done in stages. On the other hand, Iran insists on implementing its conditions within seven or even four days, and before then there will be no negotiations on the nuclear file. The exchange of messages continues.
