African Union: war crimes court for South Sudan is being set up
African Union announces South Sudan war crimes court
An inquiry has found that both government and rebel forces have committed atrocities, the AU added.
Despite the signing of a peace deal last month, conflict has continued.
The South Sudan court will use a mix of international and South Sudanese law.
However, there was no evidence of genocide, it added.
The conflict erupted after Mr Kiir accused his sacked deputy, Mr Machar, of plotting a coup.
Mr Machar denied the allegation, but then formed a rebel army to fight the government.
