Japan hit by earthquake and tsunami
Japan's most powerful earthquake since records began has struck the north-east coast, triggering a massive tsunami.
Cars, ships and buildings were swept away by a wall of water after the 8.9-magnitude tremor, which struck about 400km (250 miles) north-east of Tokyo.
Officials say at least 350 people are dead and 500 missing, but it is feared the final death toll will be much higher.
