At least two people have been killed as tornadoes struck the US states of Oklahoma and Arkansas, officials said.
The two victims were in the town of Quapaw in the north-east of Oklahoma where officials said many buildings were badly damaged.
A “mass casualty” situation was also reported in Vilonia, Arkansas, Reuters said, citing local officials.
The tornados were among several triggered by a large storm front moving through the Midwest and South.
The Oklahoma Department of Emergency Management said agency staff were headed to Quapaw to assess the damage.
Spokeswoman Keli Cain said a local official had reported that the town’s fire station was badly damaged.
“We’re hearing that there’s quite a bit of damage to the north side of town,” she said.
