“The death toll we have up until November 30 is 30,196 since the beginning of the government (of President Felipe Calderón),” said Attorney General Arturo Chavez, noting that violence has especially flared in 2010.
Mr Calderón launched a massive military crackdown on the cartels in December 2006, and since then there has been an escalating cycle of violence both between gangs fighting each other – largely for drug trafficking routes into the United States – and security forces attempting to battle them.
At least 10 of the 24 most wanted cartel leaders have reportedly been killed or captured in 2010.
The new figures however show a 6.8-per cent rise in murders in the last four months, since authorities in August reported a total toll of over 28,000.
There are almost daily incidents of beheadings, tales of torture and kidnap-murders in many northern Mexican towns.
In record violence, official figures showed on Wednesday that Mexico’s bloody border city of Cuidad Juarez had recorded 3,010 killings in 2010, including 140 policemen, in unrest linked to the drug trade.
The city of 1.3 million people opposite El Paso in the US state of Texas is a major hub for the cocaine trade. The state prosecutor’s office said the toll from fighting has skyrocketed in recent years, hitting 1,656 in 2008 and 2,754 last year.
