Syria is the only Arab state where the mass protests against the government escalated into civil war during the Arab Spring.
Over the course of three years, it turned into what some have called the worst humanitarian crisis in modern times.
Have a look at some of the images below from the country ravaged by the armed conflict:
Ghouta Chemical Attack:
An alleged nerve gas attack was reported reported outside Damascus in Syria on August 21 known as the “Ghouta chemical attack.” It was one of the worst incidents that occurred during the three-year-old civil war.
It killed at least 281 to 1,729 people including civilians and rebel fighters.
Rebel fighters are a common sight in Syria. They have found their abode in the ruins and remains of the buildings destroyed by shellings.
The infrastructure in Syrian cities such as Homs, Damascus and Aleppo is more or less destroyed to rubbles.
