Sixty one men being held prisoners by a drug cartel have been released by the Mexican army in Piedras Negras, Coahila state, located close to the USA border. Troops also found six tons of marijuana during a security sweep in a house guarded by three kidnappers. The name of the gang has not been released. Howver, the prisoners said they were forced to work for organised crime.
Mexican drug cartels are known for kidnapping and exploiting migrants trying to cross the US border. Last year, 72 migrants were massacred after they refused to work for the Zetas cartel. The same gang was accused of kidnapping bus passengers and then murdering them, when more than 100 bodies were found in mass graves.
Since President Felipe Calderon began combating cartels with military force five years ago, around 40,000 people have been killed in drug-related violence.
