It is a conflict that presents a dangerous set of challenges for those trying to document and make sense of Syria's civil war - journalists, filmmakers, activists and ordinary citizens.
The uprising began with peaceful protests for greater freedoms and democracy during the Arab Spring of 2011.
But it turned into a full-blown conflict between the government of President Bashar al-Assad and the opposition forces trying to force him out of power.
Much of the world's view of the war has been shaped by the tens of thousands of online videos posted on Youtube, Twitter and other social media.
