They laugh when their dog plays with a bear cub, and then the cub's mother arrives (3 deaths)

On Russia's Sakhalin Island in 2014, workers filmed a disturbing scene from a forest hut. Their dog was playing with a curious bear cub, as the men laughed. But the sudden appearance of a female bear accompanied by a second cub changed the atmosphere. After observing, the mother brutally charged the hut. The video stops before the tragedy is over: three men were killed, two seriously injured.
