Tens of thousands of people held in Syria's notorious prisons have been freed in the 10 days since the insurgents began their lightning advance across the country that ended with the toppling of President Bashar Assad.

But activists have begun circulating more detailed photos again online after the U.S. imposed its new sanctions, named the Caesar Syria Civilian Protection Act, after the photographer. The sanctions bar anyone around the world from doing business with Assads government or officials, and among its provisions it demands Syria release detainees and allow inspections of its prisons. Between 30 to 50 prisoners died every day at the facility where he was held, known as Branch 15, he said. Alshogres testimony about Lebanese prisoners still alive further fueled their families demands for information. Ali Aboudehn, who spent years imprisoned in Syria and now heads the Association of Lebanese Prisoners in Syrian Jails, said his group and other activists have documented 622 Lebanese prisoners held in Syria.
