There was an ongoing contact between the AU and the International Criminal Court (ICC) on the issue, he said.
Yesterday, the ICC announced the beginning of official investigations on war crimes in Darfur, in accordance with the UN Security Council resolution 1598 issued last April. Khartoum, however, had refused to hand over its citizens to be tried abroad.
Konare said he hoped next Friday's round of peace-talks in Nigeria would be final and help support a political settlement in Darfur.
The AU was keen on maintaining "a united and democratic Sudan," in spite of the country's diversities, he noted
