Japan heatwave declared natural disaster

Japan's weather agency has declared a heatwave sweeping the country a natural disaster, with at least 65 deaths recorded in the past week.
An agency spokesman warned that "unprecedented levels of heat" were being seen in some areas.
More than 22,000 people have been admitted to hospital with heat stroke, nearly half of them elderly, emergency officials say.
The heatwave shows no sign of abating, forecasters say.
