The Darfur genocide began in 2003 when two rebel groups emerged and attacked government targets, leading the Sudanese government to support Janjaweed militias who carried out violence against non-Arab groups. Over 300,000 people were killed and 2 million displaced in the resulting conflict. The UN has accused Sudan of genocide and crimes against humanity, indicting officials, while peace efforts have been hampered by divisions among rebel groups and Sudan's reluctance to implement agreements. The international community has struggled to develop an effective response to the ongoing conflict and humanitarian crisis in Darfur.
