The Mexican government has deployed soldiers to patrol a city in the northern part of the country after an attack on a police chief there.
The ex-general serving as police chief of Monclova managed to escape the assassination attempt that killed three of his bodyguards.
It's the latest attack on an official appointed to step up the fight against drug cartels.
Police say assailants in pickups opened fire on the chief as he headed home last evening. Although he was not hurt, three of the police officers guarding him died.
President Felipe Calderon has relied heavily on the armed forces and the federal police in his offensive against cartels, deploying 45,000 military personnel to drug hotspots across the country. But drug gangs have fought back with brazen attacks on police, soldiers and other government officials.
