A Texas state trooper was wounded on the Texas-Mexico border when a bullet apparently strayed from a gunbattle on the Mexican side of the Rio Grande.

Lt. Johnny Hernandez of the Texas Department of Public Safety says the trooper suffered a leg wound.

The state trooper was hit about 1 p.m. Friday while on foot patrol with the Border Patrol agent in Fronton, on the border about 105 miles upstream from Brownsville.

A U.S. Customs and Border Protection statement says the federal agent also was hit but was protected by body armor.

The trooper was in stable condition at a McAllen hospital.

Their identity has not been revealed.

Hernandez says it's unclear who was involved in the gunfight.
