ZURICH, Feb 21: A brown bear dubbed Mike by its fans has been shot and killed by gamekeepers in a mountainous border region in southeastern Switzerland after several run-ins with locals, Swiss officials said yesterday. How to deal with the bear, known as M13 by authorities, had sparked controversy between gamekeepers and environmentalists far outside the Graubuenden canton, which borders on Italy and Austria and where the animal was most often spotted.
