Veracruz: The bodies of eight people were found with their throats slit inside a vehicle in the violence-hit southern Mexican state of Oaxaca, officials said.
Local authorities told EFE that a threatening message was also found at the crime scene.
The bodies of the men -- aged 17-20 -- were found on Friday afternoon inside a gray SUV with a Mexico City license plate in Cosolapa, a rural municipality in Oaxaca.
A message was found alongside the victims with a threat directed at the Los Zetas drug cartel.
Agents with Mexico's Attorney General's Office arrived at the scene to remove the bodies of the slain people, believed to have been residents of a highland area of the neighbouring state of Veracruz.
