Prosecutors in Ivory Coast say charges have been filed against 15 top associates of former president Laurent Gbagbo, including two former ministers.

Prosecutors say the charges include harming state security, creating armed gangs and committing economic crimes.

The accused include former prime minister Gilbert Ake N'Gbo, former foreign affairs minister Alcide Djedje and the former governor of the Central Bank of West African States, Philippe-Henri Dacoury-Tabley.

Mr. Gbagbo and some of his senior associates were arrested in April, after four months of political unrest sparked by a disputed presidential election.

Mr. Gbagbo lost the November poll to Alassane Ouattara, but refused to cede power. More than 3,000 people were killed and about million displaced in the bloody power struggle that followed.

President Ouattara, who was sworn into office in May, has vowed to hold accountable all parties who committed crimes during the political crisis.

Last week, prosecutors with the International Criminal Court requested permission to investigate possible war crimes in Ivory Coast.

The United Nations has said investigators have evidence that both sides in the conflict committed war crimes and crimes against humanity.
