Tsunami port town 'completely wiped out'

The Japanese port town of Minamisanriku was completely wiped out by the Friday's tsunami, with the scale of the devastation just becoming clear some 72 hour later.

On Monday people in the town fled amid fears that another massive wave would strike, though the alert proved unfounded.

Around 10,000 people are still unaccounted for.
