White vapour billows from earthquake-hit nuclear plant
Japanese workers have been evacuated from a nuclear plant that has been hit by several explosions following the earthquake and tsunami that hit Japan on Friday. White vapour has been seen billowing from the plant.
Officials have also warned people within 20-30km (12-19 miles) of the site to either leave the area or stay indoors.
The site has also been hit by four explosions, triggering radiation leaks and sparking health concerns.
Friday's 9.0-magnitude earthquake and tsunami, which killed thousands, damaged the plant's cooling functions.
