Oklahoma tornado wreaks havoc on houses and streets

STORY: Video footage of the destruction on social media showed debris strewn across neighbourhoods and roofs ripped off a residential complex in the city of Norman, after storms had rolled through the area at around 11 p.m. local time on Sunday (February 26; 0900 GMT on February 27).

Twelve people were taken to the hospital after suffering minor injuries in the storms. None of the injuries were life-threatening, Norman Chief of Police Kevin Foster said during a news conference on Monday.

Some 13,000 homes and businesses were without power across Oklahoma, Poweroutage.us reported.
