The death toll in Japan’s earthquake and tsunami will likely exceed 10,000 in one state alone, an official said Sunday, as millions of survivors were left without drinking water, electricity and proper food along the pulverized northeastern coast.

“This is Japan’s most severe crisis since the war ended 65 years ago,” Prime Minister Naoto Kan told reporters, adding that Japan’s future would be decided by the response to this crisis.

Although the government doubled the number of soldiers deployed in the aid effort to 100,000, it seemed overwhelmed by what’s turning out to be a triple disaster: Friday’s quake and tsunami damaged two nuclear reactors at a power plant on the coast, and at least one of them appeared to be going through a partial meltdown, raising fears of a radiation leak. . .
