A massive tornado ripped through the southern suburbs of Oklahoma City, Monday afternoon.
Helicopter images showed large tracts of Moore, Okla., completely leveled by what the National Weather Service says was at least an EF-4 tornado with winds in excess of 166 mph. On video aired by KFOR-TV, emergency personelle could be seen sifting through rubble, walking over mounds of twisted debris.
Joe Jolly, a Moore resident, told our Newscast unit that his neighborhood looked like a "war zone."
