Members of Mexico's National Guard are suspected of killing two civilians this weekend in the northern border city of Nuevo Laredo, including a pregnant teenager, a state official and local media said on Monday.
The shooting was likely due to a mix-up because a vehicle with gunmen in it had been reported in the area, the official said, speaking on condition of anonymity because the case is in federal hands. Survivors of the shooting identified National Guard members as their attackers, the official said.
A spokesperson for Tamaulipas state prosecutors said the investigation was with the federal attorney general's office, which did not respond to a request for comment.
