Calgary Fire Department responding to explosion in Mahogany

Calgary Fire Department responded to an explosion at a six-plex in the city's southeast.

Fire crews received multiple calls to the community of Mahogany around 3:15 p.m. on Thursday.

Witnesses say multiple townhouses were on fire.

The fire department says the calls were to 167 Mahogany Gardens S.E.

Fire crews arrived to flames and smoke.

EMS says it, too, was called around 3:15 p.m. to the 200 block of Mahogany Gardens S.E. for reports of a building explosion.

According to EMS, paramedics found a complex under construction had exploded.

The fire department says the townhomes are new, with some lived in and some for rent.

Three people in the area at the time were assessed and one was taken to South Calgary Urgent Care in stable condition.

A firefighter was also assessed at the scene.

Because of the proximity of the fire to other homes and how volatile the situation was, numerous neighbouring homes were evacuated.

Transit buses were brought in to keep people warm.

Nearby residents have commented on social media that there was a smell of gas in the area throughout the day where the townhouse complex is.

Police say upward of 500 homes in Mahogany could have their power and gas impacted.

Several roads in the area were closed.

The fire department is asking anyone who might have video, photos or information to contact [e-mail].
