3 dead after Texas gas line explodes

CLEBURNE, Texas -- A natural gas line in north Texas erupted Monday, killing at least three people and lighting up the sky with orange flames, officials said.

An unknown number people were missing, and officials feared the death toll could rise.

Workers apparently hit the underground line about 50 miles south of Dallas while digging on Monday, said Cleburne city manager Chester Nolen. A column of gray smoke was visible miles away.

About six people were taken to hospitals, Johnson County Emergency Management coordinator Jack Snow, said. At least three people died "and there could be more," Nolen said. An unknown number of people remain unaccounted for, Nolen said.

Laura Harlin, a resident of nearby Granbury, said she heard a "huge rumbling" that initially sounded like thunder.

"For about 10 minutes, it was so loud that it was like there was an 18-wheeler rumbling in your driveway," she said.

Also Monday, seven workers were burned when a crew drilling a natural gas well through an abandoned coal mine in West Virginia hit a pocket of methane gas that ignited, triggering an explosion. The explosion happened about 1:30 a.m. in a rural area about 55 miles southwest of Pittsburgh. A column of fire shot at least 70 feet high, but the flames fell to 40 feet within hours. Gas continued to burn late Monday afternoon.
