Mexican Police Convoy Ambushed, 11 Dead

Officers at the scene of a deadly ambush on a police convoy in Mexico's Sinaloa state.

Bullet holes in the windshield of one of the vehicles.

Local authorities say seven police officers, and four attackers were killed in the shootout.

The brazen attack resembled assaults carried out by drug cartels in the region.

Sinaloa's governor says he thinks the ambush was an act of revenge following recent law enforcement successes against local cartels.

[Mario Lopez Valdez, Governor of Sinaloa]:
"We have affected them (organized gangs) and their mobility, arrested many criminals, and made great seizures so they feel affected. This aggression is a reaction against our police."

Local cartels are in a fierce and violent fight for control of billion-dollar drug trafficking routes to the United States.
