Two people were injured on Friday afternoon when a car bomb exploded in General Zuazua, a town in northern Mexico state Nuevo Leon, official sources said, Xinhua reported.
State Security Spokesperson Jorge Domene Zambrano said in a statement that the explosion took place at 13:00 local time (1800 GMT) a few meters from the Municipal Police station. The car that exploded was parked in the police station parking lot on Thursday night.
The attack, which ruined at least three cars, and injured at least two people, was described as "an aggression to intimidate ( municipal) authorities," said Zambrano.
Residents report that the impact caused a a short power outage, which was fixed within one hour.
Pedro Munoz, head of Public security in the town, said that police in General Zuazua, which is part of the Monterrey city conurbation, had recently fired seven officers.
Car bombs are a relatively rare phenomenon in Mexico, but there were multiple deadly attacks in July and August this year that authorities have linked to the nation's drug trade.
Since December 2006, Mexico has sought to fight trafficking of illegal drugs, most of which are sent to Mexico's northern neighbor -- the United States. Some 30,000 people have died since the campaign began, according to official data published this week.
