|President Bashar al-Assad is facing international condemnation of the bloody crackdown on protesters [GALLO/GETTY]
The movement in Syria against the government of Bashar al-Assad first started following protests in the southern city of Deraa in March and has since spread across the country.
In the early stages, protesters were calling for reform and an end to corruption, but as demonstrations were met with live bullets, the rallies changed tone, calling for the fall of the government.
The United Nations says more than 4,000 people have been killed in the uprising and thousands of others arrested.
