This is the shocking moment a man is mauled by a huge tiger after trying to take a selfie with it in Thailand, writes dailymail.co.uk.

Alarming video footage shows the excited tourist crouching beside the animal and putting his arm around its back before it pounces on him. The man is knocked onto the ground and can be heard screaming in terror as the tiger`s handler desperately tries to wrestle it from on top of him. The trainer tussles with the powerful predator for a few heart-stopping seconds before he’s able to subdue it.

Earlier in the clip, the tourist could be seen confidently leading the animal by a rope as he strokes its fur - completely unaware of the brutal attack which is about to occur. A video of the incident has gone viral, with viewers taking to the comments section to share their thoughts of what happened.
