MOORE, Okla. - A monstrous tornado at least a half-mile wide roared through the Oklahoma City suburbs Monday, flattening entire neighborhoods and destroying an elementary school with a direct blow as children and teachers huddled against winds up to 200 mph. At least 51 people were killed, including at least 20 children, and officials said the death toll was expected to rise.

Block after block lay in ruins.

The National Weather Service issued an initial finding that the tornado was an EF-4 on the enhanced Fujita scale, the second most-powerful type of twister.

DETROIT - The young Detroit Red Wings have made the mighty Chicago Blackhawks look vulnerable, beating them two straight times to gain an advantage in their last playoff matchup as Western Conference rivals.

Gustav Nyquist and Drew Miller scored 31 seconds apart midway through the second period and Pavel Datsyuk restored a two-goal lead in the third to help Detroit beat the Chicago Blackhawks 3-1 Monday night and take a 2-1 lead in the second round series.

"We haven't done anything yet," Mike Babcock said.
