Hundreds of people have been protesting in the main Ivory Coast city, Abidjan, after two children reportedly died after inhaling fumes from toxic waste.
The Ivorian Prime Minister, Charles Konan Banny has offered his government's resignation after a scandal over toxic waste in Abidjan.
Ivorian television has interrupted its regular programmes to urge the protesters to give doctors access to sites where toxic waste was dumped.
Two people have died and several hundred are ill after inhaling fumes from toxic waste apparently dumped at sites in the city two weeks ago.
It said people faced serious health threats because of the toxic material. Hundreds of people are being treated.
Mr Banny, who will remain in office, was asked by Ivory Coast President Laurent Gbagbo to form a new cabinet at a meeting scheduled for Thursday.
It is unclear who dumped the waste.
