(McALLEN MONITOR) — An unidentified woman believed to be a U.S. citizen was killed Saturday night during a firefight between the Mexican military and a group of gunmen near the Plaza Niños Heroes in downtown Reynosa, said a Tamaulipas law enforcement official who asked not to be named for security reasons.

On Sunday, the Mexican military raided a stash house just two blocks away from where the woman had been killed, said a source outside law enforcement with direct knowledge.
