A tiger jumps while being trained at the Tiger Temple in Kanchanaburi province, west of Bangkok, Thailand, February 25, 2016. Thailand's controversial Tiger Temple, dogged for years by talk that it supplies the black market and mistreats its animals, is fighting to keep the big cats after wildlife authorities rejected a bid to extend a zoo licence that expired in 2013. The Buddhist temple, home to more than 100 tigers, has been investigated for suspected links to wildlife trafficking and wildlife activists have accused it of illegal breeding of the animals. Thai wildlife authorities have sent ten of the temple's tigers to a wildlife sanctuary. But the temple, which bills itself as a wildlife sanctuary, has denied links to illegal trafficking, and wants to hold on to its tigers. (Photo by Chaiwat Subprasom/Reuters)
