The Allied Democratic Forces (ADF) is the deadliest of scores of armed groups in the east of the country and the United States has formally linked it to the so-called Islamic State (IS).
The ADF began in the 1990s as coalition of armed Ugandan groups, the biggest of which comprised Muslims, who opposed Ugandan President Yoweri Museveni.
It moved into eastern DRC in 1995, establishing itself in the Rwenzori Mountains in North Kivu.
In April 2019, IS began to claim some ADF attacks on social media, presenting the group as its regional branch -- the Islamic State Central Africa Province, or ISCAP.
