A mass grave was discovered on Monday in the southern Syrian town of Daraa, at the heart of protests roiling the country for two months and virtually shut off from the outside world, an activist told AFP by telephone.
"The army today allowed residents to venture outside their homes for two hours a day," said Ammar Qurabi, of the National Organisation for Human Rights in Syria.
"They discovered a mass grave in the old part of town but authorities immediately cordoned off the area to prevent residents from recovering the bodies, some of which they promised would be handed over later," he said on the phone from Cairo.
Qurabi said the Syrian regime must bear full responsibility for the crimes committed against "unarmed" citizens and urged the international community and civil society to pressure it to stop the "brutal repression" of its people.
He said he did not know how many people were buried in the mass grave.
