In Nepal, hundreds of thousands of devotees have converged on a town for a festival which is considered the world's largest animal sacrifice. The Gadhimai festival, which happens once every five years, is taking place in Bariyapur in southern part of Nepal. More than a quarter of a million animals are expected to be slaughtered for Gadhimai – a goddess of power.Sacrifice is a seen as a way of thanking the deity for good luck, or asking her for fortune and prosperity. But the scale and method of this sacrifice has angered some Nepalis. Outside the temple grounds, a small but vocal group of animal rights activists cracked coconuts in a symbolic temple sacrifice. It was a last minute plea to the organisers of the festival to call off the event.
