Luis Moreno Ocampo, the chief prosecutor of the International Criminal Court [ICC], spoke to Al Jazeera on war crimes and the effectiveness of the prosecution process.
He admitted that it was difficult to prosecute and arrest people in power but said "we are moving in the right direction".
Weeks after ICC sought Libyan leader Muammar Gaddafi's arrest on war crime charges, Ocampo said sooner or later the Libyan leader would be brought to justice.
