International Criminal Court prosecutors will seek permission to investigate possible war crimes in Ivory Coast.
Prosecutors say they have collected enough evidence to warrant the probe and will ask ICC judges on Thursday to approve the investigation.
Investigators have been looking into claims of war crimes and crimes against humanity in Ivory Coast after a disputed presidential election in November.
Former president Laurent Gbagbo refused to cede power to the winner, Alassane Ouattara, sparking a five-month power struggle that killed more than 3,000 people and displaced up to one million.
U.N. human rights investigators have said there is evidence that forces on both sides committed war crimes and crimes against humanity during the conflict.
The political crisis ended on April 11, when pro-Ouattara troops captured Mr. Gbagbo at the presidential palace in Abidjan.
Mr. Ouattara was formally sworn in as president in May. He has promised to hold accountable all parties who may have committed crimes.
