When
In the winter of 2010-11, a "super pack" of wolves numbering up to 400 reportedly terrorized the Russian town of Verkhoyansk (population 1,300) in northern region of Yakutia, one of the remotest inhabited areas in the northern hemisphere. More than 30 horses were killed in just four days, according to local officials, and teams of hunters were established to patrol neighbourhoods and shoot the wolves on sight. Animal experts suspicious of the claims say that wolves usually form packs of no more than 10 to 15 animals, although the particularly harsh winter may have killed off the wolves' usual prey, forcing them to attack larger animals.
