Warning this video contains scenes that some viewers may find disturbing

Syrian Activists have posted video on a social media website, which shows mangled and bloodied corpses after 190 people were killed in one of the deadliest days of Syria's 16-month-old uprising. The Video said to have been shot in Douma yesterday showed bloody bodies lying on the ground. Please be warned the following video contains sensitive scenes and graphic images.

Bodies hastily wrapped in shrouds, lie on the floor. A man here holds the body of a little girl

It was reported that two whole families consisting of 26 people were killed.

This further unverified footage shows the moment the attacks took place over Douma . An Arabic speaking man is heard describing the scene of the shelling attack. This is what he said.

"Aircraft are shelling of the city of Douma…where are you, Arabs?...Douma is being shelled by aircrafts….God is greatest….Bashar…..God is greatest Douma is being shelled by aircrafts….God is greatest….Bashar…..God is greatest .

A loud explosion is heard. He shows the bomb damage and the shell on the floor of the building.

Douma has been under siege for weeks by security forces loyal to President Bashar al-Assad. It is not clear whether the bodies were of people killed by the shelling or at the hands of Assad troops and militant supporters. Rebels, apparently getting access to heavier weapons that can be used against tanks and have inflicted higher losses on Assad's forces in recent weeks.
