9 injured in apparent natural gas explosion in Denver

Firefighters say nine people were injured, one critically, by an apparent natural gas explosion in Denver.

Denver Fire Department spokesman Capt. Greg Pixley says seven bystanders were treated for minor injuries and released after a portion of a brick rowhouse was leveled in Tuesday’s blast just south of downtown. A man was critically injured, and a woman who was pulled from the debris is in stable condition.

Pixley says some of the injured were burned.

Television helicopter footage showed pieces of wood thrown like sticks and bricks spilled on the ground in front of the one-story building.
