Gunmen have killed the No. 2 security official in the home state of Mexican President Felipe Calderon, where drug cartels have launched their biggest offensive yet against the government.
State officials say assailants in two cars intercepted the vehicle that Jose Manuel Revuelta was driving and opened fire. The officials say Revuelta, two bodyguards and a bystander were killed.
Revuelta was the deputy public safety secretary of Michoacan state.
