This grisly scene is what happened when a tank containing 5,000 litres of cow blood suddenly burst and spilt its sticky contents down a residential street.
In the video, which was filmed by a horrified witness in Buenos Aires, Argentina, a river of dark red blood at least 200 metres long covers a road.
In places, blood has pooled into and filled potholes in the road while people try to reach their cars which have been marooned.
Amazingly, a brave man wearing all-white walks down the blood-drenched street while looking as if he doesn’t have a care in the world.
