Three people have been killed and nine injured in a “catastrophic collapse” of a hangar that was under construction at Boise Airport .
Authorities responded to the collapse at around 5pm on Wednesday at a privately owned steel-framed hanger under construction, Boise Fire Department Operations Chief Aaron Hummel said in a news briefing.
As of Wednesday evening, everyone who had been at the site had been accounted for, Mr Hummel added.
Three people died at the scene, and five of those who were injured are in critical condition and are receiving care at local hospitals, the city said in a statement on Wednesday.
Fire crews worked to stabilise the scene and were able to rescue multiple victims, the statement added, with Mr Hummell also telling local news that some of the rescue efforts were challenging, but a technical rescue team made entry and were able to rescue those people.
“I don’t know what caused it, but I can tell you it was a pretty global collapse,” Mr Hummel said. “It was fairly catastrophic.”
