In this photo taken Friday, September 4, 2015, a baby mountain gorilla clings to the back of its mother, on Mount Bisoke volcano in Volcanoes National Park, northern Rwanda. Rwanda has named 24 baby mountain gorillas in an annual naming ceremony that reflects the African country's efforts to protect the endangered animals, which attract large numbers of foreign tourists to the volcano-studded forests where they live.
