Although security forces successfully suppressed unrest in Burundi, armed opposition militants continued to be active. FOREBU (later renamed to "Popular Forces of Burundi" or FPB) as well as RED-Tabara joined the FNL in the DR Congo, where they became involved in the Kivu conflict and began to clash with the Armed Forces of the Democratic Republic of the Congo (FARDAC). In October 2019, RED-Tabara launched a cross-border raid into Burundi. In the next month, unidentified militants ambushed Burundian Army soldiers at the Burundi-Rwanda border, resulting in accusations by the Brundian government that Rwanda was supporting local rebel groups.
