At least 29 inmates were killed yesterday as drug cartels clashed at a prison in Mexico's Sinaloa state. Three policeman guarding the prison were injured, and 20 inmates were shot to death when one gang forced its way into another cell block and opened fire on its rivals, AP reports. One wounded man died later in hospital and eight inmates were stabbed to death later in the day. The group attacked were members of the Zetas cartel, according to local media.
In Michoacan state, headquarters of the La Familia cartel, ten federal police officers were killed in an ambush the same day. Police say the attackers blocked a highway with a truck and machine-gunned a police convoy when it stopped, the BBC reports. Several of the attackers were killed or wounded when police returned fire.
