RT has obtained a video which shows Georgian troops firing on civilian buildings in the South Ossetian capital of Tskhinval.

The mobile phone footage was apparently recorded by a Georgian soldier as he operated a machine gun. His cry of 'Yoo hoo!' as he fired on the building reminded some viewers of 'a child playing a video game' – but they were real bullets and real human targets.

An investigation into crimes allegedly committed by Georgian troops is currently underway and the exact number of casualties has yet to be established. For more on this story, click here.

Accurate estimates of the death toll have been hampered by the chaos that took over the city during the fighting. Many rushed to bury their friends and relatives in their own gardens, school playgrounds and on hospital grounds. They felt it was too dangerous to venture onto the city streets.

Please note, some viewers may find the images disturbing.
