Syrians are marking 10 years since peaceful protests against President Bashar Assad's government erupted in March 2011, touching off a popular uprising that quickly turned into a full-blown civil war. Despite a decade of fighting and a broken country, Assad remains firmly in power. Syria is economically devastated and divided into three parts. An al-Qaida-linked group dominates the northwestern Idlib province, with Turkey-backed rebels controlling stretches along the Turkish border. U.S.-backed Syrian Kurdish forces hold around a quarter of the country in the northeast. Assad controls the rest. The conflict has killed around half a million people and displaced half of Syria's pre-war population of 23 million, including more than 5 million who are refugees, mostly in neighboring countries. Here is a timeline of key events in Syria's war: ___ March 2011: Protests erupt in the city of Daraa over the detention of a group of boys accused of painting anti-government graffiti on their school walls.
