LUBUMBASHI, Democratic Republic of Congo — Renewed fighting between Democratic Republic of Congo's army and M23 rebels broke out on Sunday around a densely populated town in eastern North Kivu province, where the rebels are waging an insurgency, the army and M23 said.

The M23 captured the town of Kirumba, the economic hub of Congo's Lubero territory, at the end of June. It also seized the neighboring town of Kanyabayonga around the same time.

M23 spokesman Willy Ngoma said government forces attacked several rebel positions around Kirumba early on Sunday morning and that fighting was ongoing.

The army in a statement reported clashes with the M23 in the village of Kikuvo, around a dozen kilometers away from Kirumba.

The Tutsi-led M23 have been waging a fresh insurgency in the vast central African country's militia-plagued east since 2022.

Military efforts to push the rebels back have intensified over the past year as regionally brokered ceasefires keep failing. The latest was agreed at the end of July to start on Aug 4.

The fighting has driven more than 1.7 million people from their homes in North Kivu, taking the total number of Congolese displaced by multiple conflicts to a record 7.2 million, according to UN estimates.
