Rebel fighters associated with the Free Syria Army appear to have left Aleppo for Azaz where a ceasefire between the group and a rival rebel organisation has been called.
The Islamic State in Iraq and Syria had seized Azaz from the Western-backed Free Syrian Army, and had raised fears of a war within a war.
This footage was posted on the internet and is believed to be genuine, but because of its source and nature cannot be completely verified.
