From Huffington Post –

Tokyo Electric Power Co. spokesman Hajimi Motujuku says the blaze erupted early Wednesday in the outer housing of the reactor’s containment vessel. Fire fighters are trying to put out the flames. Japan’s nuclear safety agency also confirmed the fire, whose cause was not immediately known.

On Tuesday, a fire broke out in the reactor’s fuel storage pond – an area where used nuclear fuel is kept cool – causing radioactivity to be released into the atmosphere.

Reuters reported that two workers are missing inside the plant, and a Japanese official said that there was a crack in the roof of the No. 4 reactor.

This must be two of the fifty workers who remained on site after the other 750 were evacuated. There appear to be firefighters on the scene, so we don’t know how many are risking their lives to try and prevent a meltdown.
