COMMERCE CITY, Colo. -- Two girls were injured after a flash fire at a Commerce City duplex on Tuesday morning, the South Adams Fire Department said.

The fire was reported about 6:30 a.m. in the 6900 block of Weiman Court.

The girls, ages 15 and 11, were injured after a small explosion in a room they were in and caused a fire. Firefighters were able to get the fire under control.

The girls were taken to Children's Hospital Colorado to be treated for burns on their hands and faces. Their conditions aren't known.

Ten people from two families were displaced from the duplex, officials said.

An Xcel Energy gas emergency response team has joined the investigation to try to determine the source of the vapors that exploded.
