DENVER (KXAN) — The biggest natural gas explosion the city of Denver has seen in a decade sent 10 people to the hospital Tuesday afternoon.
KUSA, the NBC affiliate in Denver, reports the explosion happened around 2 p.m. (CST) at a quad-plex at Santa Fe Drive and Fourth Avenue in the Baker neighborhood.
The Denver Fire Department rescued one person who was trapped in the rubble. One person is in critical condition and nine other people have injuries ranging from burns to blunt force trauma.
Helicopter video from the scene shows a gaping hole in the middle of the building.
