More than 12,000 people have fled a town in the besieged rebel-held Eastern Ghouta region outside Syria's capital, Damascus, as government forces advance.
Men, women and children carrying blankets and bags were seen leaving the town of Hamouria, which has come under intense bombardment in recent days.
It is the biggest exodus from the enclave since the military stepped up an offensive to retake it last month.
At the same time, 25 lorries carrying food aid entered the town of Douma.
The International Committee of the Red Cross (ICRC) said the aid was just a fraction of what was needed in the Eastern Ghouta, where some 390,000 people are facing severe shortages of food and medical supplies.
