Authorities say the explosion of a natural gas pipeline near the small South Texas town of Falfurrias injured two people and prompted the evacuation about 150 homes. An official with the Brooks County sheriff’s office said the explosion occurred Monday night near Falfurrias, a town of about 5,000 located about 80 miles southwest of Corpus Christi. The families were allowed to return home about five hours after the explosion. Chief Deputy Urbino "Benny" Martinez tells Harlingen television station KGBT a husband and wife were injured.
