Japan PM Naoto Kan: Nuclear situation 'grave'
Japan's Prime Minister Naoto Kan has said that his country will recover from the "tragedy" of the earthquake and tsunami, but added the situation at a damaged nuclear power plant is "grave".
The alert level at the stricken Fukushima Daiichi nuclear plant has been raised from four to five on a seven-point international danger scale for atomic accidents.
The crisis was prompted by last week's huge quake and tsunami, which has left at least 16,000 people dead or missing.
