The International Criminal Court's chief prosecutor Luis Moreno-Ocampo, probing post-election atrocities in Ivory Coast, began a series of meetings Saturday with Ivorian leaders.

Moreno-Ocampo, who arrived Friday pledging an "impartial" investigation, had a mid-morning "working meeting" with Justice Minister Jeannot Ahoussou Kouadio and Abidjan's civil and military prosecutors.

Judges at the ICC, based in The Hague, appointed Moreno-Ocampo to mount an inquiry into the violence that killed more than 3,000 people during a five-month standoff following elections in November 2010.

They ruled on October 3 that there was evidence that both sides in the conflict committed war crimes and crimes against humanity -- supporters of now President Alassane Ouattara and fighters loyal to his political rival Laurent Gbagbo.

The ICC prosecutor will also meet with Charles Konan Banny, the head of the Truth, Dialogue and Reconciliation Commission tasked with probing more than a decade of conflict and promoting reconciliation in the west African nation, the world's top cocoa producer.

Moreno-Ocampo will then meet supporters of ex-president Gbagbo, who is under house arrest in the north of the country, as well as President Ouattara.

On Friday the ICC prosecutor said after meeting with Prime Minister Guillaume Soro that the investigation would focus on "who we believe are the most responsible for the crimes committed," promising to complete the investigation "as fast as we can."

Moreno-Ocampo also said he would meet with victims of atrocities, adding: "We'd like to help Cote d'Ivoire to move ahead."

Ivory Coast's long-time leader Gbagbo refused to give up power after losing the elections to Ouattara.

Gbagbo was seized by pro-Ouattara forces in April.
