A Texas state trooper was wounded on the Texas-Mexico border when a bullet apparently strayed from a gun battle on the Mexican side of the Rio Grande. The Texas Department of Public Safety says the trooper suffered a leg wound in the Friday afternoon incident, the AP reports. The trooper was on foot patrol with a Border Patrol agent in Fronton, on the border about 105 miles upstream from Brownsville. A US Customs and Border Protection statement says the federal agent also was hit but was protected by body armor. The trooper, whose identity hasn't been released, was hospitalized in stable condition. Authorities say it's unclear who was involved in the gunfight. (More Texas stories.)
