MV Wakashio has split in two and leaked 1,000 tonnes of oil into the water since it ran aground

Salvage crews were preparing to sink a Japanese-owned ship that ran aground off Mauritius, despite opposition from environmental campaigners.

The MV Wakashio broke into two on Saturday, almost three weeks after hitting a reef and spilling 1,000 tonnes of oil into idyllic waters full of marine life.
