FILE - In this Tuesday, Jan. 29, 2013 file photo, a man walks past dead bodies next to a river in the neighborhood of Bustan al-Qasr in Aleppo, Syria. The bodies of at least 65 men, many of them with their hands bound behind their back, were found on the muddy banks with the rebels and government forces blaming each other for the mass killing. On Thursday, July 25, 2013, United Nations Secretary-General Ban Ki-moon raised the death toll in Syria's civil war to more than 100,000, up from nearly 93,000 just over a month ago.
