A six-square-mile fire that destroyed four houses likely was caused by sparks thrown off by a brush hog tractor mower that struck metal, Oklahoma Citys deputy fire chief said on Thursday. The fire was brought under control after 22 fire departments answered the call, only to reignite late Thursday afternoon after gusting winds shifted southwesterly, Oklahoma City Deputy Fire Chief Cecil Clay said.
Firefighters and a National Guard Blackhawk helicopter raced to at least a dozen different fires that reignited from the menacing blaze of the previous day.
