The United States and Russia have been working to bring all sides involved in the war in Syria to the table in Geneva. They initially planned on holding a conference in May, but that has been delayed and the war has raged on.
Russia has allegedly invited representatives from the Syrian opposition's National Coalition to Moscow which has been well received but turned down.
Adviser to the opposition Munzer Aqbiq told AFP that "preset official commitments" would prevent the Syrian National Coalition from attending.
The peace deal, called Geneva II, is being organized in order to bring an end to the conflict but preconditions put in place by both sides in Syria has prevented the conference thus far.
