A new interactive by Us Vs Th3m asks users to first identify where they live on a world map, then to identify where Damascus, Syria, is on the map.
On Aug. 21, a suburb of Damascus was reportedly attacked with sarin, a nerve gas, leaving 355 Syrians dead, according to Doctors Without Borders.

Syria has been embroiled in a civil war since March 2011. More than 100,000 people have been killed, according to the latest United Nations estimate.
