A Tanzanian court on Tuesday sentenced a Chinese woman dubbed the "Ivory Queen" to 15 years in jail for her role in trafficking tusks from more than 400 elephants.

Yang Fenlan, 69, was convicted in Dar es Salaam of trafficking 860 tusks between 2000 and 2014, a haul representing the slaughter of dozens of herds of elephants.
