Mexico: Police discover three men decapitated in Acapulco over New Year's

At least five people were killed over the New Year's weekend in the Mexican resort city of Acapulco, including three men found decapitated in a central neighbourhood.

The three severed heads were found Saturday on a residential street on the roof of a car, with the bodies inside. The killings were confirmed by a law enforcement official who was not authorised to discuss the matter publicly and spoke on condition of anonymity.

Elsewhere in the city, a police officer was slain by unknown gunmen while assisting at the scene of a traffic accident near the beach and a taxi driver was gunned down in his cab.

Another police officer was shot dead on Sunday in Atoyac de Alvarez, about 90 kilometres from Acapulco.
