Japan earthquake: Foreign nationals fear radiation levels

Japan's nuclear crisis is sparking fears of radiation poisoning and many people are deciding whether to stay in the country.

Britain has advised its nationals currently in Tokyo and to the north of the capital to consider leaving the area, and to keep outside an 80km (50 miles) radius of the Fukushima plant, in line with US state department instructions.

The US has now chartered aircraft to help Americans leave Japan and authorised the voluntary departure of relatives of diplomatic staff.

France has urged its citizens in Tokyo to leave the country or move south. Two Air France planes are due to begin evacuating French nationals later on Thursday.

Foreign nationals at Haneda Airport explain why they want to leave Japan.
