Fifty-two people are dead and at least 12 others injured in a prison riot, less than 200 miles south of our border.

Relatives of inmates gathered outside the Topo Chico Prison in Monterrey Thursday.

The Nuevo Leon state governor says a fight broke out between two rival groups inside the prison.

Five of the 12 injured are in critical condition. Two areas in the facility were damaged in fires set by the inmates. Despite the incident officials say no one has escaped.
