According to media reports, the capture of Nyabiondo came after intense fighting with the APCLS militia, which is aligned with the DRC government forces. The clashes began on the morning of March 9, 2025.

Kipanda Biiri, a local leader from the Osso-Banyungu Sector where Nyabiondo is located, told Reuters, that M23 took Nyabiondo at around 3 p.m. after the fighting.

Many residents of Nyabiondo fled the violence, seeking refuge in safer areas in the western part of the province, including Kashebere.

Nyabiondo, located at the entrance of the Walikale Territory, is a strategic area and has been a stronghold for armed groups allied with the DRC government, including NDC-R led by Guidon Shimiray Mwissa.
