'Many people' evacuating Tokyo

Residents and foreign nationals are evacuating Tokyo as concern over food and fuel supplies, as well as a damaged nuclear plant continue.
The Foreign Office is to charter planes from Tokyo to Hong Kong for British nationals who wish to leave Japan. The United States and France are also organising special flights for their citizens.
Japan says it is stepping up efforts to cool overheating fuel at the tsunami-hit Fukushima Daiichi nuclear plant, but there are signs of unease amongst residents of Tokyo.
