The mutilated bodies of at least 49 people have been found in Mexico, stuffed into plastic bags and dumped on a highway near the northern city of Monterrey.

The killings appear to be the latest in a string of brutal murders linked to a continuing conflict between rival drugs gangs.

Last Wednesday, 18 people were found decapitated and dismembered near Mexico's second largest city, Guadalajara.
