White rhinoceros Bruno (R) and Gracie are seen in their enclosure at Thoiry zoo and wildlife park, about 50 km (30 miles) west of Paris, France, March 7, 2017. Poachers broke into the zoo last night, shot dead four-year-old male white rhino called Vince, and sawed off its horn in what is believed to be the first time in Europe that a rhino in captivity has been attacked and killed.
