General Dogbo Ble, the former chief of the Republican Guard, has gone on trial over the killing of a colonel during violence after elections nearly two years ago.
General Ble and seven other members of the security forces are accused of the killing, during clashes between former president Gbagbo’s supporters and those of current president Ouattara.
The general was one of the few senior military officials who did not switch allegiance to President Ouattara as the clashes drew to an end.
Mr Gbagbo is currently facing trial for crimes against humanity at the International Criminal Court in The Hague.
