How It All Began - The arrest and reported torturing of 15 schoolchildren who had written anti-government graffiti on a wall launched a series of peaceful protests in late February 2011 in the city of Deraa.

From Peace to Bloodshed - As the demonstrators became more resolute, the government crackdown worsened. On March 18, 2011, the army opened fire on protesters, killing four people. At the victims’ funerals the next day, the army shot at mourners, killing one. The jailed youths were eventually freed, but the unrest had already spread throughout the country thanks to social media. Despite calls for him to leave, President al-Assad refuses to step down.(Photo: Jalaa Marey/JINI/Getty Images)

Millions Displaced - The violence has triggered a humanitarian crisis, making it difficult for many people to access water, food, electricity and medical supplies. More than two million people have fled the war by escaping to refugee camps in neighboring countries, according to the U.N. Children make up more than half of the refugees, with three-quarters of them being under 11-years-old.(Photo: REUTERS/Azad Lashkari)

Syria - The death toll mounted inexorably, past 120,000, as Syria's nearly 3-year-old civil warfare raged on with no signs of resolution. The government of Bashar Assad did agree to eliminate its chemical weapons, but prospects for peace talks were complicated by infighting among anti-government rebels. Nearly 9 million Syrians have been uprooted from their homes, with many of them seeking refuge abroad.(Photo: AP Photo/Local Committee of Arbeen)

Claims of Chemical Attacks - Allegations about the use of chemical weapons in the civil war — which is banned under international law — were repeatedly denied by the Syrian government.
