There has been a fresh fire at the quake-stricken Fukushima Daiichi nuclear plant in northern Japan.
The new blaze began at reactor four. The plant has already been hit by four explosions, triggering radiation leaks and sparking health concerns.
More than 3,000 have been confirmed dead and thousands are missing following Friday's 9.0-magnitude quake and tsunami in north-east Japan.
The disaster has damaged the nuclear plant's cooling functions.
Officials have warned people within 20-30km of the site to either leave the area or stay indoors.
The Tokyo Electric Power Co, which operates the Fukushima plant, said on Wednesday that efforts were under way to put out the latest fire.
Further strong aftershocks continue to rock the country. An earthquake, not considered an aftershock, of magnitude 6.2 centred south-west of Tokyo shook buildings in the capital. BBC News
