Al Jazeera has the horrific details:
The video, provided to Al Jazeera by sources inside Syria, shows the mutilated body of 15-year-old Thamer al-Sahri, who was arrested for participating in an anti-government demonstration. Hundreds of residents of the Syrian town of Jeeza filled the streets to mourn his death on Wednesday, the day his body was released from the mortuary and returned to his parents, six weeks after he went missing.
The amateur video shows al-Sahri's body riddled with bullets, missing an eye, several teeth, and according to Al Jazeera's source, returned to his family with a broken neck and leg. Al Jazeera is unable to independently verify the footage due to restrictions on journalists in the country.
Al-Sahri was arrested along with his friend, 13-year-old Hamza al-Khateeb - the teenager whose brutal death caused much of the world to pay closer attention to the events in Syria.
