A home explosion outside of St. Louis, Missouri damaged more than 20 properties and reportedly left an 18-year-old with life-threatening injuries.

The St. Louis County Police Department said at least three people were hurt in the blast that rocked a neighborhood in the northern part of the county Monday morning. 

“There’s extensive damage in these homes, people will not be able to go back in there,” Black Jack Fire Department Chief Paul Peebles said, noting that five of the homes were burning. “It’s just too dangerous at this time.” 

Footage taken from the scene showed two homes leveled as firefighters doused water on their smoldering remains.

State Senator Angela Mosley said to reporters Monday that she felt the explosion in her own home multiple miles away from the scene. 

“I do live five miles away from here. I heard the explosion, felt the explosion and things in my house did fall. I thought it was a tree that fell, but unfortunately it was an explosion and thank God that nobody lost their life,” she said. 

Police said the St. Louis Regional Bomb and Arson Unit and the Blackjack Fire Protection District were on-scene Monday to assess damage and investigate the source of the explosion.
