A prison riot in eastern Bolivia claimed the lives of 31 people, including one child, dpa reported.
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.
"They used machetes, knives, poles, shivs, improvised weapons and gas cylinders that provoked the fires in the pavilion," Romero said Friday.
Santa Cruz Governor Ruben Costas declared two days of mourning for the victims of the Palmasola prison.
"One of the saddest things that we should bear in mind is that this nightmare is being lived by about 450 children who are deprived of their freedom because of their fathers," said Monsignor Sergio Gualberto, Catholic archbishop of Santa Cruz.
He said there was no occupational therapy or policies for rehabilitation and reinsertion.
"They've practically been consigned to oblivion," he said.
