Authorities say a car exploded near the offices of a newspaper in a northern border state where two drug cartels are fighting for control.
The Tamaulipas state government says in a statement an explosive device aboard a car blew up late Monday and that no one was injured.
The blast broke windows and caused other damage to buildings, including the offices of the Expreso newspaper. Several nearby cars were also damaged.
Authorities didn't say who they suspect was behind the attack but local media reported the Zetas drug cartel had claimed responsibility.
Since 2010, the Zetas and Gulf cartels have been fighting over control of the drug routes running into much of southern Texas, turning Tamaulipas into one of Mexico's most violent states.
