Monterrey, Mexico – An explosion at a plaza in a Monterrey suburb in northeastern Mexico injured 15 people.
Authorities blamed the Saturday night attack Sunday on drug cartels targeting the civilian population to cause chaos.
Police believe the attackers threw a grenade at the main square in the town of Guadalupe. But Adrian de la Garza. director of the Nuevo Leon state investigations agency, says investigators are still trying to confirm the type of explosive involved.
Deputy state health director Francisco Gonzalez says six children were among the injured, the youngest being age 3. Gonzalez says the injuries aren't life-threatening.
It was the fourth such attack in two days in the area around the city of Monterrey, which has been reeling from a turf war between the Gulf and Zetas drug gangs.
