In its broadcasts, Televisa offered no explanation as to why it might have been targeted. According to a local press report, the state attorney general said an explosive device was thrown at the headquarters of the traffic police in the city about the same time.
This is the third time in two weeks that Televisa, which covers general news, has been targeted by bomb attacks. The region is suffering battles for control by drug cartels.
Two weeks ago, another car bomb exploded in the parking lot of the local police headquarters in Ciudad Victoria. On August 15, a hand grenade was thrown at the building of Televisa in Monterrey, the largest city in Mexico's north. There were no injuries reported, according to press accounts. However, there was damage to the building and to vehicles used for remote transmissions.
On August 14, unidentified assailants fired a grenade at Televisa offices in Matamoros, Tamaulipas state, news reports said. The grenade was fired from a nearby pedestrian bridge, the Mexico city-based newspaper reported, causing minor property damages but no injuries.
And on July 5, what appeared to be a sophisticated car bomb detonated in Ciudad Juarez, another northern Mexico town heavily influenced by narcotics traffickers and corrupt local officials. That car bomb seems to have been the first set off by radio remote control.
