ST. LOUIS (AP) — Strong storms caused damage in parts of the middle U.S. Tuesday and spawned tornadoes in Kansas and Iowa, including one that left two people hurt.

An EF-1 tornado touched down shortly after 6 a.m. near the northeastern Kansas town of Richland, the National Weather Service said. The twister reached speeds of up to 100 mph (161 kph) and was on the ground for about 20 minutes, the service said.

Two people were injured when their RV flipped over during the tornado. Details about the injuries were not immediately available. Buildings and trees also were damaged in the neighboring town of Overbrook.

In central Iowa, a barn was demolished and other buildings were damaged after a tornado touched down in a rural area of Dallas County. The weather service also reported ping pong ball-sized hail in Bloomfield, just north of the Missouri line. There were no immediate reports of injuries.
