Luis Moreno-Ocampo, Chief Prosecutor at the International Criminal Court (ICC), undertook a significant step in his office's investigation of the situation in Darfur, Sudan, on November 20, 2008, when he requested Pre-Trial Chamber I to issue an arrest warrant against three named individuals. These individuals, whose names have remained confidential, were commanders of rebel groups in Darfur that had carried out an attack on September 29, 2007 against African Union Mission in Sudan (AMIS) peacekeepers stationed at the Haskanita Military Group Site.
