On the night of June 6–7, 2014, the village of Mutarule, near Luberizi, in South Kivu, Democratic Republic of the Congo, was attacked.

It is thought the attack was revenge for the death of a cattle herder who died in a failed robbery.

The South Kivu region of the Democratic Republic of the Congo hosts people who fled Burundi during the civil war and multiple rebel groups including the Democratic Forces for the Liberation of Rwanda (FDLR) and the National Liberation Forces (FNL).

An armed militia is stationed about 12 miles (19 km) from the village, but the perpetrators of the attack were never determined.

[1] Several pregnant women were among the dead, which numbered 27 according to South Kivu governor Marcellin Cishambo.

[1] A United Nations (UN) statement said "fierce fighting" between the Bafuliru and Barundi had taken place the night before the attack.
