A prison riot in eastern Bolivia claimed the lives of 31 people, including one child, the interior ministry and medical officials said Saturday according to dpa. The 18-month-old was among the charred victims found after a clash Friday between rival groups in Santa Cruz de la Sierra, where some inmates have their children live with them. Another 52 detainees were injured, many from stab and burn wounds, hospital director Abel Duran said. Two are in critical condition. Inmates of rival sections were fighting for control of space and leadership in Bolivia's biggest prison, Interior Minister Carlos Romero said.
