Advances by Assad regime forces into opposition-held Eastern Ghouta are causing many people to flee.
Witnesses said people had fled areas where regime forces had seized ground at the eastern periphery of the opposition enclave and were seeking shelter in areas in the heart of Eastern Ghouta.
The Syrian observatory for human rights estimated that between 300 to 400 families had fled, adding that regime bombardment was focused on the town of Mesraba.
