Congo's health minister says it's a "dark day" for everyone fighting the deadly Ebola outbreak after rebels shot and killed two medical agents with the Congolese army who had been helping health officials.
The statement late on Saturday says Mai Mai rebels surged from the forest and opened fire on the unarmed agents with the army's rapid intervention medical unit at an entrance to Butembo city.
It is not immediately clear whether this is the first time health workers have been killed in this outbreak.
The ministry says the daytime attack appeared premeditated.
Congo's latest Ebola outbreak is taking place in what health workers have compared to a war zone, with multiple rebel groups active in the region.
The number of confirmed Ebola cases has now reached 200, including 117 deaths.
