HOUSTON A natural gas pipeline exploded in northeastern Texas on Tuesday, injuring three people, authorities said.
Helicopters were dispatched to the scene, about 145 miles northeast of Amarillo, to ferry the injured to hospitals, according to the Lipscomb County Sheriff's Office.
The number of workers missing after the blast was not available, the sheriff's office said.
This is the second natural gas pipeline blast in Texas in as many days.
One worker was killed on Monday afternoon when a construction crew working near Cleburne, Texas, struck an underground pipeline.
