A large amount of scaffolding collapsed Friday outside a building under construction in Houston, the Texas city fire department said.
Video from the scene showed piles of metal lying on the ground outside a roughly seven-story building. The collapsed scaffolding appeared to cover a large section of a city block.
It was not immediately clear if there are any fatalities as a result of the incident or if anyone was still trapped. Video, however, did show at least person being carried on a stretcher to get medical help.
The Houston Fire Department reported that the first crews arrived within three minutes after the collapse was reported around 11:10 a.m. (12:10 p.m. ET).
Within about 30 minutes, more than 30 units — including several heavy rescue personnel — were already on-site.
Firefighters could be seen walking around the scene, in some cases getting underneath the rubble of scaffolding.
