Both sources told Reuters the CODECO militia was responsible for the killings, which took place about 0200 GMT at the Savo camp in Ituri province.

CODECO fighters have killed hundreds of civilians in Ituri in recent years and forced thousands to flee their homes, according to the United Nations. Recent attacks have also targeted displaced persons camps.

“I first heard cries when I was still in bed. Then several minutes of gunshots. I fled and I saw torches and people crying for help and I realized it was the CODECO militiamen who had invaded our site,” said Lokana Bale Lussa, a camp resident.

“We have counted more than 60 dead and (more) seriously injured,” he said.

Charite Banza Bavi, president of the local humanitarian group for the Bahema-North area, put the death toll at 63.

The Savo displacement site was home to about 4,000 people in December, according to the U.N. migration agency.

CODECO’s fighters are drawn mainly from the Lendu farming community, which has long been in conflict with Hema herders.

A government spokesman could not immediately be reached for comment.
