BENI, Democratic Republic of Congo (Reuters) -Suspected Islamist militants killed at least 26 people in an attack in the town of Oicha in eastern Democratic Republic of Congo on Monday night, its mayor said on Tuesday.
He attributed the killings to the Allied Democratic Forces (ADF), a Ugandan armed group based in eastern Congo which has pledged allegiance to Islamic State and mounts frequent attacks.
The attack occurred around 11 p.m. (2100 GMT), said Nicolas Kikuku, the mayor of Oicha, which is in North Kivu province. Four people were wounded and taken to hospital, he said.
"It's sad because this time there was no warning," said local civil society activist Janvier Kasereka Kasayirio, who confirmed the attack and also blamed the ADF.
He said local youths were angry on Tuesday after police took the bodies away from them to transport to the morgue, and that young protesters burned several vehicles at an aid distribution site.
The U.N. World Food Programme said that three trucks used by its contractors had been torched, and that it was investigating the incident.
Uganda and Congo launched a joint military operation two years ago to try to root out the insurgents. Uganda's army said last month it had succeeded in killing more than 560 fighters and destroying some of their camps.
