At least 34 civilians were killed Sunday in ethnic violence in restive eastern Democratic Republic of Congo, authorities said.

"The provisional toll is 34 civilians killed," said local official Joy Bokele, referring to the attack by a Nande ethnicity militia on the Hutu village of Luhanga.

"They started by attacking the FARDC (DR Congo military) position. While they were attacking the FARDC, another group was executing the population with bladed weapons or bullets," Bokele said.

He added that the attack was carried out by a Nande militia group and that one of the attackers was killed in the clashes.

Tension between the Nande and Hutu peoples have been high in the restive east, shaken by two decades of fighting over land, ethnic tensions and mineral riches.
