A gruesome new video clip from the war in Syria appears to show a rebel soldier named Khalid al-Hamad cutting an organ from the body of a dead pro-Assad soldier and biting into it. Al-Hamad told Time
he did this after finding a video on the dead man's phone that shows him assaulting a naked woman and her two daughters. Horrible videos like these are used as propaganda tools, but there are concerns they are causing retaliatory violence to spread across the country. Brent speaks to Tracey Shelton
, a senior correspondent for Global Post who has seen countless videos and photographs from the battlefields of Syria and Libya.
