The Japanese owner of a bulk carrier, which grounded and spilled 1,000 tonnes of fuel oil on the island of Mauritius, said there has been little progress on removing the ship's remaining stern section.

The Mauritius government was hopeful that what is left of the wreck of the 203,000-dwt Wakashio (built 2007) would be removed early this year.

In a statement to mark one year since the disaster, owner Nagashiki Shipping said that progress has been halted by poor weather and sea conditions.
