Syria has been locked in a vicious civil war since early 2011 when the regime of Bashar al-Assad cracked down on pro-democracy protests which erupted as part of the Arab Spring uprisings, with unexpected ferocity.
Since then, more than a quarter of a million victims have been killed and more than 10 million displaced across the war-battered country, according to the UN.
The Syrian Center for Policy Research, however, puts the death toll from the six-year conflict at more than 470,000 people.
