Mexico has seen one of the worst single atrocities in its long-running drug war with the discovery of at least 49 mutilated bodies near the northern city of Monterrey. Mexican police say the victims’ remains were stuffed into bags and dumped on a highway. The killings are believed to be a part of a string of drug gang murders across Mexico. Last week, 18 people were found decapitated and mutilated in the city of Guadalajara.
