Suspected Islamists killed at least 20 civilians in attacks on Sunday and Monday in Democratic Republic of Congo's Ituri province, a local official and a local rights group said.
The attackers were believed to be members of the Allied Democratic Forces (ADF), the sources said. The ADF is a Ugandan militia that has been active in eastern Congo since the 1990s and has killed scores of civilians in village raids.
"The situation remains tense in Mangusu, an area two kilometres (1.24 miles) from Komanda. The enemy killed 17 civilians there before burning down houses and looting many of the residents' belongings," said Moise Ucini, a representative of the governor in Komanda, on Monday.
