Al-Jazeera reporter Noor Al-Dajir in Tehran: The diplomatic path through mediators continues. In this framework, there is an American proposal that wants to combine Iran's proposal, which includes seven conditions with the American nuclear requirements, including the issue of highly enriched uranium and testing, and the implementation of the agreement will 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 issue. The exchange of messages continues.
