The Syrian government has rejected a report which claims to show the systematic torture and killing of around 11,000 prisoners, calling it "politicised" and an attempt to undermine peace talks in Geneva.
The 31-page dossier was released on Monday and contains 55,000 pictures of corpses bearing signs of torture and strangulation.
The former war crimes prosecutors who authored the report said Syrian officials could face war crimes charges as a result of the evidence gathered.
However, Syria's Ministry of Justice said the report was "lacking objectivity and professionalism".
A ministry statement on Syrian state television said: "Releasing the report one day before the 'Geneva 2' conference provides categorical evidence that its goal...is to undermine efforts aimed at achieving peace in Syria."
