A total of 34,612 people have died in drug-related killings in Mexico in the four years since President Felipe Calderón declared an offensive against cartels shortly after taking office, officials said tonight.
Killings reached their highest level in 2010, when there were 15,273 deaths, up from 9,616 the previous year.
At a meeting with anti-crime groups at which the government presented a data system to track drug-related crimes, Calderón said 2010 had been “a year of extreme violence”.
The office of federal security spokesman, Alejandro Poire, said the four-year figure included 30,913 execution-style killings, 3,153 deaths in shootouts between gangs, and 546 deaths involving attacks on authorities.
