The estimated death toll from Monday’s massive tornado in Oklahoma stands at more than 91 people, including 20 children. Some 200 people were also wounded. [ Editor’s Note: After broadcast, the Oklahoma medical examiner revised the death toll down to 24, including 7 children.] The storm tore through the Oklahoma City suburb of Moore, leveling two elementary schools, a hospital and scores of homes. Rescue crews continue to dig through the rubble in a bid to find survivors. One witness said the tornado was so powerful it tore open a cellar door.

Ricky Stover: “We thought we died, because we were inside the cellar door, we locked the cellar door once we saw it coming, it got louder, and next thing you know, you see the latch coming undone, and we couldn’t reach for it, and it ripped open the door. And just glass and debris started slamming on us. And we thought something — we thought we were dead, to be honest.”

Monday’s storm marked the deadliest tornado to hit the United States since 161 people were killed in Joplin, Missouri, two years ago. President Obama has declared a major disaster area in Oklahoma, ordering the deployment of federal aid.
