Amnesty International has called for a UN-backed investigation into the violence in Syria, saying the regime's crackdown on pro-democracy protesters may constitute crimes against humanity.The group has documented several cases of torture, deaths in custody and arbitrary detention in a new report.
All relate to a military sweep in the western village of Tell Kalakh in May.
Amnesty says the UN Security Council must refer Syria to the International Criminal Court (ICC) in the Hague.
Syrian human rights groups have said that more than 1,350 civilians and 350 security personnel have been killed across the country since protests began in mid-March against the repressive rule of President Bashar al-Assad, who is fighting off the most serious challenge to his family's four decades in power.
The Syrian government has not responded to the report, but it claims that many of those who have died were the victims not of the army, but of armed criminal gangs.
Syrian state media has also reported on what it said was a large pro-government demonstration in Tell Kalakh late last month.
