Just saw this on facebook. They say this was angel of death. What you see is a person wearing a long white robe and he picked up a dead body with one hand and walked towards a crowd. At the beginning I thought this is nothing but after watching for few times, something just seems strange. Maybe he is just a really strong man?

Google translate from a local news:
"When mercenaries Basyar Al-Assad regime is mad killing demonstrators, suddenly figure out the body of a man dressed in white from the military side Basyar Al-Assad. The man lifted the martyr victims Basyar mercenaries killed Al-Assad in peace when there is behind the armed forces. The white-robed man looked calmly lifted the boy was martyred by one hand only.
Who is the white-robed man? There is still a question."
