Charles Ble Goude, an ally of Ivory Coast ex-President Laurent Gbagbo has made his first appearance at The International Criminal Court (ICC).
Mr Ble Goude, a former minister, has been charged with committing crimes against humanity during clashes that followed the 2010 election.
He denies all the charges – including accusations that he led a militia.
His extradition last week infuriated supporters of Mr Gbagbo, who is also at The Hague court, awaiting trial.
The warrant against Mr Ble Goude was unsealed in September.
Prosecutors at the court accused him of being responsible – “as indirect co-perpetrator” – for four crimes against humanity, including rape, murder and persecution.
The crimes are said to have been committed during between December 2010 and April 2011, following the disputed election.
Some 3,000 people lost their lives in the crisis, after Mr Gbagbo refused to concede victory to his rival, Alassane Ouattara.
Mr Ble Goude was the head of the Young Patriots, an organisation of Gbagbo loyalists that was blamed for a campaign of violence against those seen as Mr Ouattara’s supporters.
In an interview last year with the BBC, Mr Ble Goude said that he had only organised rallies and meetings and never run a militia.
