From this story in the Moscow News:
Hunters in Yakutia, north east Russia, are joining forces to track down and destroy a 400-strong pack of wolves that has so far killed 30 horses. The predators pose a threat to human life and a single pelt will meet a reward of 10,000 roubles, a district administration source told RIA Novosti. However, some scepticism may be appropriate. Wolves usually form packs of not more than 15-20 animals, and a group of 400 would be difficult to sustain.
