Several children have been pulled out of the rubble alive at a school in the suburbs of Oklahoma City. The Plaza Towers Elementary School in Moore, Okla., took a direct hit as a massive tornado flattened entire neighborhoods. Rescue workers lifted children from the rubble before they were passed down a human chain and taken to a triage center set up in the school's parking lot.
