Disaster in Northeast Japan
Developments in Japan
A new fire broke out in the No. 4 reactor at the Fukushima Dai-ichi nuclear plant, but the cause was not immediately known. Earlier in the day Tuesday another fire broke out in the same reactor's nuclear storage pond, causing radiation to be released into the air. All but about critical 70 workers were evacuated from the plant.
Radiation levels in areas around the plant rose briefly Tuesday before appearing to subside by evening, according to officials.
The Japanese government ordered 140,000 people living within 20 miles of the plant to seal themselves indoors to avoid exposure. Commercial air traffic was banned throughout the area.
Officials have only confirmed about 3,300 deaths, but that number is expected to be significantly higher. Search teams found few signs of life in coastal areas hardest hit.
