Authorities in Arlington, Texas were responding to reports of collapsed buildings and flying debris after strong winds swept through the southern U.S. state on Tuesday night.
"Our units are currently assessing the structures, triaging potential patients, and moving to other reported locations," the city's fired department said, while the police were determining the extent of damages.
There were no immediate reports of casualties.
