The US Coast Guard has used cannon to sink a crewless Japanese ship that drifted to Alaska after the 2011 tsunami, BBC reported.
The coast guard earlier said they would hold off scuttling the Ryou-Un Maru after a Canadian fishing boat claimed salvage rights.
But a Canadian official later said that the Bernice C had been unable to tow the 200ft (61m) Japanese "ghost ship".
The boat had no lights or power and was viewed as a danger to other ships.
It was thought to be at the vanguard of a stream of tsunami debris that has been drifting east since last year's disaster hit Japan.
