Congolese forces said, they had killed 25 rebels since launching an offensive against them late last month in an eastern region also struggling with an Ebola outbreak.
Seven soldiers from the Democratic Republic of Congo had also died since the campaign to root out the Allied Democratic Forces (ADF) militia began on 30th October, the general in charge of the operation, Jacques Nduru, said.
He said “the army had seized four of the group’s positions around the eastern city of Beni in North Kivu province”.
Regular militia attacks have hampered efforts to contain Ebola across the area.
The ADF, originally a Ugandan rebel group, has been operating along the Congo and Uganda border for more than two decades.
It is one of a number of armed factions active in east Congo long after the official end of a 1998-2003 war.
Several of ADF’s attacks have been claimed by militant, but the extent of their relationship remains unclear.
