Rescuers went building to building in search of victims and thousands of survivors were homeless on Tuesday after a massive tornado tore through the Oklahoma City suburb of Moore, wiping out whole blocks of homes and killing at least 24 people. The death toll was lower than initially feared, but nine children were among the dead, including seven who died at Plaza Towers Elementary School, which took a direct hit on Monday in the deadliest tornado to strike the United States in two years.
