A hiker walking with their dog in Jarfjord, Sør-Varanger, was bitten in the arm by a bear and is now receiving medical treatment; authorities warn against approaching bears.

A brown bear was filmed running through downtown Loimaa after emerging from the Loimijoki River, one of several recent sightings in Southwest Finland this spring.

The brown bears hibernated for only two months due to the warm winter conditions, according to zoo officials.

The attacks are being attributed to a shortage of acorns in the bears’ natural habitat, forcing them to wander into populated areas in search of food.
