Three bears at a Ukrainian zoo tore a man "limb from limb" after he fell into their enclosure, local media reports.

The 22-year-old man was drunk and trying to take close-up shots of the Siberian Brown bears at Mykolaev city zoo when he lost his footing, witnesses said, acording to Channel 5 television.

The three bears charged the man immediately, tearing him "limb from limb" as he tried to escape, according to the station, quoted by the Deutsche Presse-Agentur news agency.

The man was dead before keepers could separate the animals from their victim.

The brown bear is highly territorial and among the world's largest land carnivores.
