The Allied Democratic Forces is a Ugandan Islamist rebel group based in western Uganda and eastern Democratic Republic of the Congo. Some refer to the group as ISIS-DRC as a chapter of IS-CAP, but this terms is broader and tends to include non-ADF rebels. It is considered a terrorist organization by the Ugandan government and the United States. The group is sanctioned by the United States and the United Nations Security Council. Originally based in western Uganda, the ADF has expanded into eastern DRC where nearly all of its fighting has occurs. Most ADF fighters are Ugandan Muslims from the Baganda and Basoga ethnic groups.
Since the late 1990s, the ADF has operated in the Congo's North Kivu province near the border with Uganda. From Wikipedia
