They are meeting in a bid to broker a temporary ceasefire in the city of Aleppo, where fighting between government and rebel forces has escalated in recent weeks, leaving hundreds dead.
"We are being forced to leave, but our condition has deteriorated to the point of being unbearable," Hussam Ayash, an activist in the town, told the Associated Press news agency. "We withstood for four years but we couldn't any longer."
Meanwhile a monitoring group said 11 children had been killed in a barrel bomb attack by government forces in a rebel-held neighbourhood of Aleppo. They were among 15 people killed in the incident, the Syrian Observatory for Human Rights said.
The UN says Russia, who has been supporting the Syrian government in its offensives, has agreed to a 48-hour pause in Aleppo to allow in much-needed aid.
But the organisation added it was still waiting for agreement from other parties fighting on the ground. In another development, the US has urged "strong and swift action" after a UN investigation concluded that Syria used chemical weapons against its own people.
