The conflict began as a largely peaceful uprising against Assad's rule in March 2011. It gradually became an armed conflict after some opposition supporters took up arms to fight a government crackdown on dissent. Over the past year, the fighting took on sectarian overtones with predominantly Sunni Muslim rebels fighting Assad's regime that is dominated by Alawites, an offshoot Shiite group. Over 100,000 people have died.
