Japan tsunami: Military begins search for bodies
US and Japanese military personnel are taking part in a three-day search of north-east Japan for the bodies of people missing since the tsunami.
Helicopters and ships are leading the search of the shorelines and the mouths of major rivers which remain inaccessible by foot or road.
The BBC's Mark Worthington said the search teams would be staying out of the exclusion zone around the Fukushima nuclear plant.
