TOKYO (AP)-- As of 9:15 p.m. CDT Monday: Japan spokesman says 4th reactor at damaged nuclear plant is on fire, releasing more radiation.
Japan's nuclear safety agency says it suspects an explosion at a nuclear power plant may have damaged a reactor's container and fears a radiation leak.
An agency spokesman, Shigekazu Omukai, says the nuclear core of Unit 2 of the Fukushima Dai-ichi plant was not damaged in the explosion early Tuesday.
But the agency says it suspects the bottom of the container that surrounds the generator's nuclear core might have been damaged.
Another agency spokesman, Shinji Kinjo, says that "a leak of nuclear material is feared."
Japanese police say the official death toll from last week's massive earthquake and tsunami has risen to 2,414 (as of 8:45 p.m. CDT Monday).
Police said Tuesday that a big share of the deaths were in Miyagi prefecture, where 1,254 people are confirmed dead.
The number of people officially missing is at 3,118. But regional officials said they believe that tens of thousands may have been swept away by the tsunami that devastated a long stretch of Japan's northeastern coast Friday.
