Officials in Venezuela say dozens of people have been killed or injured in a prison riot in the southeastern state of Bolivar. Details from VOA’s George Mee in our South America Bureau. "The riot occurred at El Dorado Prison, a maximum security facility located in the jungles 700 kilometers southeast of Caracas. Some of the victims were burned to death and others stabbed with home-made knives. The wounded victims of the uprising have been taken to the nearby mining town of Tumailimo for medical treatment. Many are reported in serious condition. Justice Minister Halion Calidooso announced the casualties before flying to El Dorado with the national prison director to investigate the incident. The clash began when the inmate went for breakfast at 5:30 in the morning. Officials say the riot was apparently caused by rivalry between longer term inmate and a group that had been transferred to El Dorado from another prison last November.
