20 civilians have died in a village attack in eastern Democratic Republic of Congo

20 civilians died in an attack on a village in the eastern Democratic Republic of the Congo (DRC), according to local authorities.

Authorities blamed the Allied Democratic Forces (ADF) rebel group for the attack, saying its fighters first attacked a rival group of Congolese militia members before killing inhabitants in the village of Lisasa.

Local administrator Donat Kibwana, from the Beni territory in North Kivu province, put the “preliminary death toll” at 21. The figure was confirmed by the head of the Buliki area, where Lisasa is located, according to the AFP news agency. A local NGO called Cepadho said in a statement that of the 21 killed, 15 were women.

“Everything happened yesterday between 8pm and midnight – the armed men carried out a raid,” local leader Kalunga Messo told the Reuters news agency on Saturday by phone. “They killed our brothers without mercy.”

About six years ago, the ADF started to attack villages, killing people using machetes and guns and abducting hundreds of others. The ADF has never claimed responsibility for attacks.

Several attacks attributed to the ADF have also been claimed by ISIL (ISIS), although United Nations experts have found no evidence of a direct connection between the two groups.

A year ago, the Congolese army launched a large-scale campaign against the ADF.

In response, the group abandoned its bases, split into smaller, more mobile groups and retaliated against civilians.

On October 21, hundreds of prisoners escaped from a jail in Beni following an attack by armed men. Police blamed the ADF while ISIL took credit for it.

The latest attack comes only days after the ADF killed 19 people in the remote village of Baeti on Wednesday night. The village’s church was torched, as were about 40 homes.
