Gunmen attacked the offices of the El Norte newspaper in San Pedro Garza Garcia, a city in the northern Mexican state of Nuevo Leon, over the weekend, but no one was injured, the State Investigations Agency, or AEI, said.
The attack occurred around 6:15 p.m. Sunday in the Fuentes del Valle district of San Pedro Garza Garcia, which is in the Monterrey metropolitan area, the AEI said.
Four people were working inside the building when the attack occurred, but they managed to get out.
The masked gunmen doused the building's entrance with gasoline, set it on fire and fled from the scene, the AEI said.
Municipal, state and federal law enforcement agents responded to the attack, securing the area around the newspaper's offices.
Firefighters put out the blaze and were assisted by state emergency management office personnel.
The vehicle used by the gunmen was abandoned nearby, the AEI said.
El Norte, which is published by Grupo Reforma, is one of the most influential dailies in Monterrey, the capital of Nuevo Leon, and has now been attacked five times.
The newspaper's office on Monterrey's Avenida Revolucion was attacked with a grenade on Sept. 20, 2010, and sustained minor damage.
El Norte was attacked on Jan. 10 and March 31 of last year, but no one was injured in the attacks.
Two of El Norte's offices were attacked with grenades on July 10 in Monterrey, but no one was injured.
The first attack targeted the newspaper's office on Avenida Revolucion in the southern section of the state capital.
A subject entered the parking lot and threw a grenade, leaving the pin on the ground.
No one was working in the offices because it was early, but some employees were in the rear of the building.
The second attack happened at El Norte's office in Libertad, a neighborhood on the east side of Monterrey.
Gunmen threw a grenade at the office and fired at least 10 shots at the building with an AK-47 assault rifle.
Employees were working in the building, but no one was hurt.
No criminal organization had claimed responsibility for the latest attack as of Sunday night, the Reforma newspaper reported on its Web site.
Mexico, where nearly 80 journalists have been murdered since 2000, is considered one of the most dangerous countries in the world for members of the media.
