Every five years, the world's largest animal sacrifice takes place at the Gadhimai Temple in Nepal. The month-long festival has raised controversy due to the large number of animals killed – up to 500,000 over two days. This year, Humane Society International (HSI) successfully petitioned India's Supreme Court to stop animals at the border. In coordination with Animal Welfare Network Nepal, HSI sent a delegation to patrol the site and confiscate any animals brought in illegally. The team also met with Nepal's president and prime minister to discuss the situation. To date, more than 2,500 animals have been saved.
