Civil war and chemical weapons in Syria
Two years later, Syria is in the middle of a civil war-driven by ethnic, sectarian and regional conflicts. On one side-a disparate group of rebels united by their common goal of removing President Bashar Al-Assad from power.
On the other-a government that has ruled Syria for decades, now fighting for its survival.
The UN estimates around 70,000 people have died in the fighting, and another three million are homeless. Many more have fled across the border to neighboring Turkey, Lebanon and Jordan.
And just a few days ago, there were reports of chemical weapons being used in the northern city of Saraqeb.
