Seven people, including four firefighters, hurt in gas explosion at Dallas apartments

Four Dallas Fire-Rescue firefighters and two civilians are seeking treatment at Parkland and Baylor hospitals following a gas explosion at an apartment complex in Dallas.

At around 10:21am, Dallas Fire-Rescue was called to an apartment complex at 5726 Highland Hills Drive for a gas leak. Firefighters smelled gas and confirm there was a leak in the area. While they were investigating, the leak exploded and severely damaged the two-story apartment building, resulting in a fire.

The explosion caused a partial collapse of the apartment building.

Four firefighters and three civilians were injured in the blast. All individuals were transported to hospitals for treatment of their injuries. Three firefighters are listed in critical condition. All others are stable.

There is no information on what caused the explosion, as this will be a joint investigation involving Dallas Fire-Rescue along with multiple local, state and federal agencies, to determine exactly what happened.
