Incredible pictures show the huge tornado which ripped through Oklahoma City on Monday, killing two people and reducing homes to rubble.
The hardest-hit areas were about 70 to 80 miles southeast of the city, where a tornado more than a mile wide ripped through the area.
One person was killed in Garvin County, about 60 miles south of Oklahoma City, when a home was destroyed by a twister, authorities said.
Another person was killed near the town of Connerville, about 110 miles south of Oklahoma City.
The National Weather Service described that twister as large and destructive, warning people: “You are in a life-threatening situation.”
At least one other tornado was reported to have hit Oklahoma, the service said.
Local news showed photographs of two of the destroyed homes by the twisters.
The National Weather Service issued a tornado watch for large parts of southern Oklahoma into western Arkansas.
It also said two tornados have been reported in Nebraska.
