"There are several documents on which the three opposition platforms agreed. They are still not official agreements. But there is a significant progress," the source said.
According to the source, there are several different working papers.,
"One is a 12-point paper on the future of Syria. The other one is 15 points relating to the issues of a transition period," the source added.
The 12-point paper, also known among participants of the negotiations as Naumkin-Ramzy paper, is a document distributed by the UN side to the Syrian sides at the March round of the Intra-Syrian talks. The paper summarizes points of commonalities between the opposition and the Syrian government and suggests what the core principles for a political solution in Syria should be. The paper, published on the UN website, names such principles as sovereignty, independence, territorial integrity of Syria, democracy, non-sectarianism, rejection of terrorism among other provisions.
