Japanese fishing vessel spotted adrift off the west coast of Canada

A Japanese fishing vessel swept away by the March 2011 tsunami has been spotted adrift off the west coast of Canada.

An aircraft patrolling the seas off British Columbia saw the 15m (50ft) vessel floating 275km (170 miles) from the Haida Gwaii islands on Friday.

It is believed to be the first large item from the millions of tonnes of tsunami debris to cross the Pacific.

No-one is believed to be on board the ship, registered in Hokkaido, Japan.
