Four men and three women were gunned down Sunday in Torreon, one of the largest cities in the northern Mexican state of Coahuila, prosecutors said.

The shooting occurred in Vicente Guerrero, a poor neighborhood in the southern section of Torreon, the Coahuila state Attorney General’s Office said.

“In the incident reported, it has been confirmed that four males and three females died,” the AG’s office said.

The “bodies of five people were found inside a vehicle,” the AG’s office said.
