Herd of cows commit mass suicide [View all]

"Farmers in Switzerland have been left baffled after a herd of cows jumped to its death off of a 50metre-high cliff last week.

The 13 Herens cows broke through their pen and through several lines of security around their pasture before running toward a cliff and either falling or throwing themselves off of the 50metre drop near Levron in Valais on Wednesday."
