MONTERREY, Mexico (AP) - The offices of a major Mexican newspaper group have come under attack for a third time this month.
Several masked, armed men broke into a branch office of the El Norte newspaper near the northern city of Monterrey, poured out gasoline and ignited it. The newspaper's website says none of the 15 people working in the Sierra Madre office were injured. Firefighters quickly extinguished the blaze.
El Norte is a sister publication of Mexico City's Reforma newspaper.
Police say the attackers fled. No gang has claimed responsibility for the attack but drug cartels have increasingly targeted Mexican newspapers to discourage coverage of drug violence.
Two other outlying offices of the paper were attacked with grenades and gunfire on July 10.
