A car bomb left outside a police station in the town of Acambaro in western Mexico wounded 5 people, prosecutors in the violence-wracked state of Guanajuato said.

Another explosion, apparently a 2nd car bomb, occurred in the nearby town of Jerecuaro. Although nobody was wounded, the force of that second blast was enough to blow the tile roof off a building, blacken the facades of surrounding stores and set alight a police patrol pickup truck.

The near-simultaneous attacks in two different towns located about a half-hour away from each other suggested the involvement of drug cartels that have been fighting bloody turf battles for years in Guanajuato.

A resident who witnessed the aftermath of the blast in Acambaro said that among the injured was a woman and her daughter who were waiting for a bus. Authorities had said earlier that all of the three wounded were police officers.
