MOORE, Okla. (AP) — I left the office as soon as I saw the tornado warnings on TV. I had photographed about a dozen twisters before in the past decade, and knew that if I didn't get in my car before the funnel cloud hit, it would be too late.

MOORE, Okla. (AP) — Spotlights bore down on massive piles of shredded cinder block, insulation and metal as crews worked through the night early Tuesday lifting bricks and parts of collapsed walls where a monstrous tornado barreled through the Oklahoma City suburbs, demolishing an elementary school and reducing homes to piles of splintered wood. At least 51 people were killed, including at least 20 children, and those numbers were expected to climb, officials said.
