The ship at the centre of a toxic waste scandal which has killed at least 10 people in Ivory Coast has been given permission to leave Estonia. The Probo Koala sailed for the Baltic after more than 500 tonnes of waste from its tanks was dumped at several sites in Abidjan in August.
The Dutch firm which chartered the ship said it had contracted an Ivorian company to dispose of the material.
The ship was impounded in Estonia at the request of the Ivorian authorities.
