Canadian ferry owner Marine Atlantic has revealed a bunker leak from a tanker in Port aux Basques.

It said the 3,600-dwt North Atlantic Kairos (built 2008) had suffered a spill on Sunday.

The company added it had been working with the Canadian Coast Guard "regarding observation and response activities." A boom was placed around the tanker.

The vessel is operated by North Atlantic Refining, which was also working to contain the spill.
