The violence in Nuevo Laredo, across from Laredo, Texas, prompted the temporary closure of the highway, which is a major artery for travel and commerce between the United States and Mexico.
The Tamaulipas state government said in a statement that the armed confrontations began early Saturday when troops killed eight suspected criminals on the highway. Soldiers seized a truck and high-caliber weapons, it said.
An hour later another shootout broke out nearby in which two suspects were killed, along with a woman who was traveling in her car, authorities said.
Nuevo Laredo Mayor Carlos Canturosas said Saturday night viaFacebook that the highway, which handles nearly half of the export-import cargo between Mexico and the United States, had reopened.
