ACAMBARO, Mexico — A car bomb left outside a police station in the town of Acambaro in western Mexico wounded three people, prosecutors in the violence-wracked state of Guanajuato said Thursday.
They said another explosion, apparently a second 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.
''A woman and a child were going to catch the school bus, and the woman was also seriously wounded,'' said shopkeeper Francisca Acevedo."They took her away in an ambulance."
Acevedo said ''it was a big explosion, very strong. We thought a tree had fallen in front of the house.''
And in another attack in Guerrero state, to the south, two municipal policemen were killed and four were wounded in a massive shootout with suspected drug cartel gunmen, who were equipped with three bullet-proof vehicles, a machine gun and what appeared to be bombs dropped by drones.
Soldiers later killed 14 of the attackers; three soldiers were wounded in the running confrontation.
