The Canadian military has investigated a mysterious pinging sound coming from the sea floor in a remote region of the Arctic, officials have told the BBC.

A military aircraft conducted various multi-sensor searches in the area, officials said on Friday.
But the military says it is so far unable to explain the cause of the "acoustic anomalies".
