I don’t know where the video is from, but it looks India, Pakistan or Bangladesh-ish to me.
The CCTV footage shows a standard, South Asian chaotic intersection traffic. About 40 seconds into the video, a bicyclist is shown being run over by a truck. When the tire goes over the bike, it appears to explode, complementing the shock factor of the video.
Props to Best Gore member @momox for the video:
