The state's coordinating group of state and federal law enforcement says the confrontations occurred throughout the day yesterday in Madero and Tampico.
The statement did not name the criminal groups or say if the attacks were related.
Tamaulipas, one of Mexico's most violent states, has been hit by infighting in the once dominant Gulf Cartel, which has also come under attack from its rival, the Zetas.
