Syrians and Lebanese wave the pre-Baath Syrian flag, that was adopted by the Syrian revolution during the uprising, during a demonstration on March 15, 2015, in Martyr's Square in the Lebanese capital Beirut. The protesters marched to mark the fourth anniversary of Syria's conflict, which began with anti-regime protests in mid-March 2011 and spiralled into a bloody war after a harsh government crackdown on demonstrators.
