Mexico sends troops to north

MEXICO CITY — Mexico's government is sending hundreds of soldiers and federal police to a northern region where drug cartel violence has been on the rise and a prominent businessman was recently killed, authorities announced Friday.

The forces are going to the Comarca Lagunera region that straddles Coahuila and Durango states, the Interior Department said.

The announcement came three days after Interior Secretary Francisco Blake met with the governors of the two states. He discussed the possibility of sending federal forces to the region but also urged the governors to step up efforts to root out corruption in state and municipal police forces.

Local businessmen demanded stepped up security in the region after a prominent rancher with ties to the Lala dairy company was killed.
