"The negotiations with the leaders of six armed groups in Damascus, Daraa, Homs provinces are in progress. Thirty applications to join a ceasefire are already signed with the leaders of the armed groups," according to the newsletter.
It was added in the newsletter that the preliminary agreements to join ceasefire had been reached with the elders of the six settlements in the province of Damascus.
The Russia-US brokered ceasefire was backed by the Syrian government and dozens of opposition groups on the ground. The Daesh and the Nusra Front (outlawed in Russia) are not part of the truce.
