Mexico's deadliest prison brawl in many years was a bloodbath in which inmates attacked each other with hammers, cudgels and makeshift blades, authorities said Friday, underlining yet again the power that drug cartels wield inside many of the country's lockups, according to AP. Jaime Rodriguez, governor of the northern state of Nuevo Leon, said 60 hammers, 86 knives and 120 shivs were used in the previous day's fighting at the Topo Chico prison in Monterrey, where 49 inmates were hacked, beaten or burned to death, and a dozen more injured. At least 40 of the victims "died from wounds from stabbing and cutting weapons, blows from hammers and clubs," Rodriguez said at a news conference. Authorities also seized various kinds of contraband items from marijuana and cocaine to televisions and USB memory sticks.
