A car bomb on Thursday in front of a local government's public security office in central Mexico injured three police officers, the secretariat said, in an uncommon type of attack in one of the country's most violent states, Paralel.Az reports citing Reuters.

One of the injured, a female police officer, was transported to hospital, while two male officers suffered more minor injuries.

"There has been a car bomb attack outside the public security building of Acambaro, there are 3 injured police officers," the secretariat said in a message on Facebook.

Acambaro is located in the central state of Guanajuato, that has led the homicide rates in the country in recent years amid an intensification of armed confrontations between criminal groups and security forces.

The attack also caused "property damage to the building, four neighboring houses and seven vehicles," the secretariat added.

No civilian injuries were reported, it said.
