Suspected Islamist militants killed at least 22 civilians with knives and machetes in an overnight raid on villages near the town of Beni in eastern Democratic Republic of Congo, a local official said on Wednesday.
Jean-Paul Katembo, head of the Bulongo commune, said the known death toll stood at 22, including women and children.
Several more villagers are believed to have been kidnapped, he said, blaming the Allied Democratic Forces (ADF), a Ugandan militia active in eastern Congo since the 1990s.
Elsewhere, a group of men hacked graves into the earth to bury the victims as other villagers stood by and sang in mourning.
On May 17 Uganda announced it had agreed to share intelligence and coordinate operations against the rebels, but that it would not be deploying troops in Congo.
