Eleven giant pyres of tusks were set alight Saturday as Kenya torched its vast ivory stockpile in a grand gesture aimed at shocking the world into stopping the slaughter of elephants. Lighting the fire in Nairobi's national park, Kenyan President Uhuru Kenyatta demanded a total ban on trade in ivory to end the "murderous" trafficking and prevent the extinction of elephants in the wild. / AFP PHOTO / CARL DE SOUZA
