Assailants fired a dozen gunshots at a building housing the newspaper El Debate in the embattled northern Mexico state of Sinaloa, the media outlet said Friday.
The newspaper is based in the state capital, Culiacan, where rival factions of the Sinaloa Cartel have been staging bloody battles.
The newspaper said it found at least four bullet impacts on the building's walls, and more gunfire hit newspaper vehicles parked in front of the offices late Thursday. The paper said that no one was injured.
The Mexican Media Alliance, a press freedom group, called it "a direct attack against press freedom and right of the public to be informed."
El Debate said that the assailants arrived in two vehicles and stopped briefly in front of the building. One gunman got out and opened fire with a rifle, before they sped off.
