Thirteen people were killed and some 65 injured in a prison riot on Saturday in the central Mexican state of San Luis Potosi, local officials said. A fight broke out before daybreak among prisoners in a cell block in the La Pila prison in the state capital of San Luis Potosi, and state police re-established control by the morning, officials said. Concepcion Tovar, head of the state's prison system, told reporters that at least 100 inmates participated in the riot, which she blamed on a gang that had been harassing and robbing other inmates, according to a report of Reuters.
