Abiy admitted Eritrean troops were in Tigray after months of denial
On 23 March 2021, Abiy Ahmed told parliament that Eritrean troops had entered Tigray, the first official acknowledgment after months in which their involvement had been denied. In the causal graph this event strengthens State Repression, a driver that strengthens Number of victims of intentional homicide per 100,000 population, by sex (victims per 100,000 population) — a worsening welfare path.

On 23 March 2021, Abiy Ahmed told parliament that Eritrean troops had entered Tigray, the first official acknowledgment after months in which their involvement had been denied. The EHRC–OHCHR joint investigation later recorded the Eritrean Defence Forces as a party to the conflict alongside the Ethiopian National Defence Force, Amhara Special Forces and allied militia, and found reasonable grounds to believe that all parties committed serious violations to varying degrees. Its findings included unlawful killings, torture and ill-treatment, arbitrary detention, sexual and gender-based violence, forced displacement and attacks affecting refugees; the report said some violations may amount to war crimes and crimes against humanity, depending on the act and legal elements. A later UN commission reported that ENDF and EDF troops conducted joint operations and said Eritrean involvement significantly exacerbated the conflict and the scale and intensity of violations. In late November 2020 Abiy had told parliament that “not a single civilian was killed” in the operation; in March 2021 he said soldiers found to have raped or looted would be held accountable. No cited source shows that he ordered specific crimes committed by Eritrean soldiers.

The UN commission documented joint ENDF–EDF operations and explicitly said Eritrean forces significantly exacerbated the conflict and the scale and intensity of violations, violations by state forces and their allies directly strengthen state repression. Weight basis: Joint ENDF–EDF operations were found to have significantly exacerbated the scale and intensity of violations against civilians, including unlawful killings, torture and arbitrary detention. Weight 0.83 is the pack's qualitative severity class for this event, not an empirical coefficient.

The joint investigation documented forced displacement and other abuses by parties to the Tigray conflict and identified the EDF as a conflict party; because displacement has multiple perpetrators and causes, the mechanism is material but attribution to Eritrean participation is less exclusive than the conflict-intensity link. Weight basis: EHRC–OHCHR documented forced displacement among the violations committed during the conflict by the parties, including conduct involving Eritrean forces.
