M23 accused of brutal mining abuses in eastern DRC’s coltan hubs

The armed group M23 has committed “extrajudicial executions,” torture, forced labor, and arbitrary detentions in eastern Democratic Republic of Congo (DRC) mining sites, according to a new report. The abuses target artisanal miners in North Kivu’s coltan-rich Rubaya region—a key global supplier of the mineral used in electronics.

Documented killings and systemic violence

Amnesty International’s investigation reveals 18 artisanal miners were executed in two separate incidents in Rubaya and the Lomera gold mine in South Kivu. Survivors and families described a pattern of brutality: miners beaten to death with blunt objects, shot execution-style, or abducted and later found dead.

  • Ten victims were bludgeoned to death, two shot at point-blank range, and six abducted before their bodies were recovered.
  • Miners reported being beaten for requesting breaks, refusing to hand over ore, or minor rule violations.
  • Over 20 miners were held in underground cells, subjected to three daily beatings by M23 fighters.

Forced labor and coercive control

Beyond killings, the report documents systematic coercion in coltan mining operations. Miners described a climate of fear where compliance was enforced through violence. Some reported being forced to work without pay under threat of severe punishment.

“The M23 has weaponized control over critical mineral supply chains,” a conflict analyst noted. “These abuses are not isolated—they are integral to their revenue model.”

Denial and international scrutiny

M23 leadership has consistently denied allegations of extortion or human rights abuses, calling such claims “fabrications” to undermine their legitimacy. Yet the report, based on eyewitness testimonies and forensic evidence, contradicts these claims.

The findings add pressure on global tech industries dependent on Congolese coltan. “Consumers deserve to know if their devices are tainted by bloodshed,” the advocacy group stated.

What happens next?

Analysts warn the abuses could escalate unless international intervention addresses both the humanitarian crisis and mineral trade accountability. “The world cannot ignore the human cost of its demand for coltan,” an expert concluded.
