Japan Nuke Plant Explosion

AP Reports:

SENDAI, Japan -- An explosion at a nuclear power station tore down the walls of one building Saturday as smoke poured out and Japanese officials said they feared the reactor could melt down following the failure of its cooling system in a powerful earthquake and tsunami.

"We are now trying to analyze what is behind the explosion," said government spokesman Yukio Edano, stressing that people should quickly evacuate a six-mile (10-kilometer) radius. "We ask everyone to take action to secure safety.".
