Mexico's drugs war

Since 2007, Mexican gangs killed more than a hundred thousand people. The Mexican president pledged to put an end to this.
Last Friday, Mexican security forces killed forty-two drug cartel henchmen. It was one of the bloodiest shoot-outs in a decade of gang violence. One policeman also lost his life in the three-hour gunfight.
The killed were members of Jalisco New Generation which is a powerful drug cartel in the area. This cartel killed more than two dozen police officers since March.
