Mexico City ? Federal police rescued two kidnapped news cameramen in northern Mexico on Saturday, five days after they were seized by drug traffickers in a bid to get their employers to broadcast cartel messages.

Local journalists in Mexico have long been under siege from drug traffickers, but Monday’s kidnapping of journalists with national television networks, including the nation’s largest Televisa, shocked many Mexicans. Two other journalists abducted the same day were released earlier.

Public Safety Secretary Genaro Garcia Luna said Javier Canales of Milenio Multimedia Television and Alejandro Hernandez of Televisa were freed before dawn Saturday in the city of Gomez Palacio, where the men had been held in a residential area.

Garcia Luna, who was accompanied by the two cameramen at a Mexico City news conference, said the Sinaloa drug cartel was responsible for the abductions and that the kidnappers guarding the reporters escaped.

The Sinaloa drug cartel is run by Joaquin “El Chapo” Guzman, Mexico’s most-wanted drug lord.
