17 people have been shot dead by gunmen who broke into a drug rehabilitation center in a northern Mexican border city. The attackers on Wednesday broke down the door of the El Aliviane center in Ciudad Juarez. They lined their victims up against a wall and opened fire. Authorities had no immediate suspects or information on the victims.

Ciudad Juarez is Mexico's most violent city, with at least 1,400 people killed this year alone. Most of the homicides are tied to drug gang violence. President Felipe Calderon sent thousands more troops and federal police there earlier this year, but this has done little to stem the raging violence. The city is home to the Juarez drug cartel, which is battling other gangs for trafficking and dealing territory.
