Fighters of the Allied Democratic Forces (ADF) staged two raids Saturday night in the North Kivu region bordering Uganda, Teddy Kataliko, leader of the civilian administration in Beni district, told AFP.

According to his account, rebels at Mangboko burnt a lorry driver in his vehicle and killed six other civilians, while in Oicha, they killed one person and abducted 15 others -- for a total death toll of eight.

Beni district administrator Donat Kibwana said seven people were killed and 15 people were abducted, including 10 children.

Army spokesman Captain Mak Hazukay also put the death toll at seven.

Kataliko denounced the army as ineffective, saying: "It is not normal that the army cannot manage to keep the population safe," but Hazukay insisted that soldiers had reacted quickly to stop the rebel incursions.

The ADF, which US authorities designated a terror group in 2001, is a militia created by Muslim rebels to oppose Ugandan President Yoweri Museveni but which also operates in the DRC.

It is blamed for a string of attacks in the region since 2014 that have killed at least 700 civilians, and 15 Tanzanian peacekeepers in a December assault last year.
