Dakar - Democratic Republic of Congo military "elements" are responsible for digging at least 42 mass graves in three Kasai provinces after clashes with alleged militia members in recent months, the United Nations said as experts were appointed on Wednesday to look into a growing crisis that has killed hundreds and displaced more than a million people.
Human rights have deteriorated alarmingly due to the "brutal and disproportionate repression against the Kamuina Nsapu militia by the Congolese defense forces," the UN Joint Human Rights Office in DRC said in a new report.
Congolese soldiers have killed more than 428 people, including women and 140 children, in the once-calm Kasai provinces as of June, the office said.
The militia has killed at least 37 people during that time, it said.
The UN said it regrets the "lack of efforts" to ensure independent investigations into the serious human rights violations that have included sexual violence and the use of child soldiers.
The Catholic church has estimated that more than 3 300 people have died in the fighting in the Kasai provinces since the military killed the militia's traditional chief in August.
DRC's government didn't immediately comment on the new UN report but has blamed the militia for the mass graves, which the UN says number at least 80.
The report also says allegations have come forth since April that a self-defense group, the Bana Mura, may be supported by DRC's military and that it reportedly has committed a number of executions against civilians associated with the Kamwina Nsapu militia.
The UN human rights chief on Wednesday appointed a three-member panel to investigate alleged abuses in the Kasai region.
