On Friday 8 May 2020, in the Rweru sector of Bugesera district in the Eastern Province, a group of fishermen from Burundi illegally crossed into the Rwandan waters in Lake Rweru.
According to RegionWeek, While Rwanda Defence Force was ordering the fishermen to return back to their country, Burundian soldiers intervened from their side and started shooting at RDF; which retaliated.
Rwanda Defence Force suffered no casualties during the gunfire exchange and the attackers returned back to Burundi.
The borderline between Rwanda and Burundi is a known demarcation line in the middle of Lake Rweru that is easily identifiable using technology like the GPS.
According to various reports, Rwanda supports and trains Burundian rebels particularly Résistance pour un État de Droit au Burundi (Red Tabara), a group operating in South Kivu.
Burundian President Pierre Nkurunziza accused Kagame of being behind another attack on November 16, in which unknown assailants killed at least eight Burundian soldiers at a military post in Mabayi, Cibitoke province. Since then both Burundi and Rwanda have deployed forces to their mutual border.
