While weather forecasters and news channels reported on the magnitude of the tornado that hit Oklahoma city, local residents used their smartphones to capture footage of the twister and shared it on social media networks like Instagram, YouTube and Twitter. Many inhabitants heeded the city's warning of strong winds and sought shelter, but some remained in the shadow of the tornado and shared terrifying footage of the dark, three-kilometre wide cone of wind that swept through heavily populated suburbs.
According to reports the tornado has already claimed 91 lives. Emergency crews and residents continued to comb through the rubble of debris the tornado has left behind and it is expected that the death toll will rise.
