2 more officers shot to death in Mexico's most dangerous city for police as cartel violence rages: "It hurts"

Two police officers were shot to death in the embattled Mexican city of Celaya amid a wave of targeted attacks that authorities said Thursday were likely carried out by a drug cartel.

A total of 18 Celaya police officers have been shot to death so far this year, making the city of a half million inhabitants probably the most dangerous city in the hemisphere for police.

"This is something that worries us a lot, and more than that it hurts," President Andrés Manuel López Obrador said of the attacks.
