An activist from Austrian NGO "Four Paws" tranquilises bears that are are seen in a cage at a private zoo located next to a restaurant in the Kosovo town of Prizren, about 90 km (56 miles) southwest of the capital Pristina, May 22, 2013. Kosovo has launched a campaign, helped by "Four Paws", to seize wild bears held in restaurants and private zoos, responding to concerns over their dwindling numbers in the Balkan country's mountainous border areas.
