Heavy fighting broke out between the Rwandan and Congolese military in troubled eastern DR Congo after an incursion by Rwandan troops, according to a Congolese army spokesman.
Investigations are underway to see if the clashes occurred because of a problem with border demarcation.
The fighting occurred on Tuesday “on Congolese soil” close to the Rwandan border at the foot of Mount Nikeno in North Kivu province, Major Guillaume Djike told AFP.
A senior officer in the DRC army, on condition of anonymity, told AFP: “There have been deaths on both sides.”
Congolese army patrols exchanged fire with Rwandan army positions some 100 metres (yards) inside DR Congo before the two countries’ capitals contacted each other and intervened, according to a military source.
