Two cranes collided at a construction site in Austin, Texas, on Wednesday, injuring at least 22 people, authorities said.
Footage posted by TV station KVUE showed two cranes, 150 feet high, tangled several stories above a building under construction a few miles north of downtown in a rapidly growing neighborhood that includes residential, retail and office space.
At least 22 people were hurt, including at least seven who were being treated and prepped for transport to a hospital, Austin-Travis County EMS reported.
It is not yet known what caused the collision. Battalion Chief Mark Bridges said: 'This just happened to be two cranes working, we’re not sure how or why, but they did get entangled.'

At least eight ambulances were headed to the scene.
Commander Mike Benavides told The New York Times one person was seriously injured.
Battalion Chief Bridges added: 'Since they are attached at the top, we don’t want the wind to cause further problems. Right now, no one is trapped or injured and we are doing our best to monitor the scene.'
TV footage had shown one of the crane operators still inside the crane cabin, although it did not appear to be damaged.
Authorities had described it as a 'crane collision' and a 'structural collapse'; they later stressed it was not a collapse.
All of those injured were workers at the site, officials said. Most of the injuries occurred as they left the site, KVUE reports.
The development also includes a children's hospital near the accident site.
