Fire officials say six people have been taken to hospitals after a gas explosion started a major fire in a San Francisco Bay Area suburb. The explosion in the Hayward area obliterated at least one home and sent heavy smoke into the air. Video shows a home sitting under a blue sky before it suddenly exploded, sending wood and debris skyward. A spokesperson for Pacific Gas & Electric Co. said construction workers damaged an underground gas line around 7:35 a.m. Thursday. The utility stopped the gas flow at 9:25 a.m. The explosion occurred shortly afterward.
