Mexico City — The death toll in a prison riot in northern Mexico has risen to 16 with the death of three more inmates.
The government of the northern border state of Nuevo Leon earlier said 13 prisoners died in the riot, which police put down with gunfire. The government said Wednesday three more died of their wounds.
Tuesday's riot saw inmates take guards hostage, beat them and threaten to throw them off the roof of the state prison in Cadereyta.
Spokesman Aldo Fasci said several hours of attempted negotiations failed and police were unable to quell the riot with non-lethal force. He said prisoners at the facility are separated by gang affiliation, but that one group didn't fit because members had worked for a number of organizations.
