The Death of Karine Buisset

Drone Strike · Himbi District, Goma · 11 March 2026

Focus War Crimes
Operation High confidence
Location Himbi, Goma
Release 18 March 2026
Karine Buisset was a 54-year-old French national and UNICEF Programme Specialist for Protection Against Sexual Exploitation and Abuse (PSEA). She had been working in Goma since at least early 2025, documenting sexual violence by armed actors in eastern DRC. She had planned to return to France in December 2025. Her mission was extended. At approximately 04:00 on 11 March 2026, two drone strikes hit the Himbi district of Goma. Buisset was asleep in the apartment of Christine Guinot, UNICEF's head of security in the DRC, who was absent. The strike destroyed the apartment. Buisset did not survive. Two other people were also killed: an M23 combatant and a private security agent. The existence of these two victims was confirmed by the DRC government communiqué of 13 March 2026; neither has been identified by name in any source reviewed (DRC Government / Ministry of Justice, 2026). The strike was not claimed. No party has issued an official denial

Open-source assessment

01
High

Attribution points to FARDC

Acoustic evidence, CH-4B fragmentation pattern, ACLED data attributing 60+ 2026 drone strikes to FARDC, and the post-strike communications pattern all converge on a single actor.

02
High

Compound inside the M23 leadership cluster

The Belgian compound sits 50–100 metres from the Kabila family residence, adjacent to documented residences of Bisimwa, Nangaa Yobeluo, and General Makenga.

03
High

FARDC's own coalition implicitly admitted responsibility

Wazalendo spokesperson Jules Mulumba celebrated on 11 March. Deputy Willy Mishiki publicly claimed the strike in parliament.

04
Flag

GPS jamming gap may have created the precision window

OFAC sanctions on 2 March 2026 explicitly cited RDF GPS jamming systems. If confirmed, GPS drift cannot explain why this compound was struck.

05
High

Private contractors in the chain of command

FARDC drone operations run through Agemira (Bulgarian-registered) and Vectus (Erik Prince links). Question for OCLCH.

06
Dis

The assassination narrative is rejected

Veritasinfo's claim that Buisset was killed by Rwandan intelligence is structurally inconsistent with acoustic evidence and MONUSCO report.

Key questions for OCLCH

This report does not make a formal legal finding of criminal liability — that is the function of OCLCH. It maps the factual record against the IHL standard to identify which questions the investigation must answer.

01

What building or compound did FARDC operators believe they were striking?

02

What pre-strike imagery or intelligence existed for the Belgian compound? Was it positively identified as a humanitarian residence?

03

Who authorised the Himbi strikes? At what command level?

04

Did FARDC's targeting process include any UN security coordination records for the Himbi district?

05

Was GPS jamming active or inactive during the strike window? Was a jamming gap communicated to drone operators?

06

Were the Agemira or Vectus contractors flying the drones? What were their rules of engagement?

07

Who are the two unnamed other victims — the M23 combatant and the private security agent?
