The soldiers were in Roma, Texas when two shots were fired from across the border, the Texas Department of Public Safety said.
The suspected shooters are believed to be gunmen from a drug cartel. The incident occurred in the same area where Fox News witnessed tracers from a suspected cartel machine gun while embedded with Texas Rangers.

No injuries were reported in Thursday’s incident and the Texas Rangers are investigating.
