Wind-driven wildfires in Oklahoma have killed at least four people and resulted in 142 others being taken to local hospitals with fire-related injuries, the state's Department of Emergency Management said Sunday.

Oklahomans are assessing the devastation after wildfires damaged or destroyed hundreds of homes around the state during a severe weather outbreak.

The wildfires came from a historic storm that is crossing the nation, spawning deadly tornadoes in Missouri. In Oklahoma, the storm on Friday brought 60 to 70 mph winds. The sustained gusts knocked down power lines, ripped off shingles from houses, broke tree limbs, felled street signs, caused road closures and filled the sky with dust.
