Control of the Yarmouk refugee camp south of Damascus has pitted Palestinians fighting with rebels against Palestinians from the Popular Front for the Liberation of Palestine-General Command loyal to Assad
Over 1,000 Palestinian refugees crossed into Lebanon in the past 24 hours.
Videos published on the Internet appear to show people streaming out of the Yarmouk refugee camp near Damascus on Monday, which Syrian rebels claim to have captured.
Reuters is unable to independently verify the video content, but one shows a steady stream of people carrying bundles and luggage as they walk down a street covered with debris.
