Opposition activists have posted a video purporting to show at least 51 muddied male bodies alongside a river bank in the rebel-held Bustan al-Qasr neighbourhood of Aleppo.
The video, which is too graphic to post, follows a man walking along a river bank past dozens of male bodies with their hands tied and blood coming from their heads.

The 58-year-old man was stabbed in the neck as he approached the Altrincham Islamic Centre in Manchester.
The body is set to allow national team players to wear the poppies on the pitch as it backs down in a row over the memorials.
