New grenade attack on Mexico TV channel in border city

The offices of Mexican broadcasting giant Televisa were hit by a grenade for the second time in two months in the gang-plagued border city of Matamoros, authorities said Thursday.

Assailants tossed the grenade from a vehicle Wednesday night, causing damage to the building`s facade, but nobody was injured, said an official in the Tamaulipas state prosecutor`s office.

The same building of the world`s biggest Spanish-language television network was attacked on February 6, when unknown assailants threw a grenade that wounded two guards.

The city, which lies across the US border from Brownsville, Texas, has endured a surge of violence in recent weeks attributed to internal strife within the Gulf drug cartel.

On March 8, gunmen opened fire on the convoy of Mayor Leticia Salazar, who escaped unscathed. A dummy grenade was found in the city hall`s parking lot a month earlier.

The northeastern state of Tamaulipas has seen some of the most gruesome acts of violence in Mexico`s drug war, which has left 100,000 people dead or missing across the nation since 2006.
