Japan earthquake: Aerial footage of devastation
Footage filmed on 13 March of Miyagi and Iwate prefectures shows flattened buildings, fires still burning and stranded ships.
Police have warned that the death toll in tsunami-hit Miyagi prefecture alone could exceed 10,000.
The tsunami that followed the 8.9-magnitude earthquake wreaked havoc along a huge stretch of Japan's north-east coast, sweeping far inland and devastating a number of towns and villages. Powerful aftershocks are continuing to hit the region.
