Approximately a dozen people were injured in a house collapse in Syracuse, New York, at around 4 p.m. local time on Tuesday, June 18.

According to the Associated Press, CBS News and Syracuse.com, Chief Michael Monds of the Syracuse Fire Department told reporters that multiple 911 calls were made about a possible “explosion” and the collapse of the two-story home. The investigation is ongoing.

“The building was indeed collapsed,” said Monds, per CBS. “It was a very dangerous scene. There were power lines down and the dangerous odor of gas.”

Media reports state that either 11 or 13 people were injured, including two in “very serious” condition.

Multiple victims were reportedly found outside the building, with firefighters having to pull one young person from a car that was located under the rubble. 

Up to 13 people are thought to have been living in the home but all have been accounted for, authorities said, Syracuse.com reported.

Per CBS, a late-night news release from the fire department reported that 11 of those injured had been taken to a local hospital, with officials adding on Wednesday morning that the 11 were in either stable or critically stable condition.

According to ABC News, victims were found with burn and crush injuries. While a young child was found in a car near the collapsed building, three other people were discovered in places inside the residence.

“Certainly, we’re in a good spot right now after conducting our searches,” Monds said, per local TV station WSYR. “When you look at the condition of the building, to know that there were 13 people inside that have made it out is remarkable.”

“The mayor and I spoke about how miraculous it is to have all 13 alive right now at this point,” Monds said.

WSYR reported that Syracuse Mayor Ben Walsh said a family of seven lived in the home and another family of six had been visiting at the time of the collapse.
