“The talks are difficult, it’s too early to give any judgment on any results,” the source said.
The source added that an overall position had not been reached yet and that of the 38 negotiators from both sides, the majority was supportive though some were refusing to support proposed initiatives.
The negotiations are taking place between January 26 and 29 and have brought together Syrian government officials, representatives from opposition parties and UN Special Envoy for Syria Staffan de Mistura.
The first stage of the talks, held on January 26-27, saw meetings between opposition groups. The second stage, taking place on January 28-29, is expected to be used to hold negotiations between the Syrian opposition and a government delegation.
On Monday, Syrian President Bashar Assad said the Moscow talks should be considered as preparation for a conference to settle the conflict in Syria.
