Escalation in Eastern DR Congo: M23 Rebels Advance Despite US-Mediated Peace Efforts

The fragile peace in eastern Democratic Republic of Congo (DRC) has shattered in recent weeks as Rwanda-backed M23 rebels launched a new offensive, capturing strategic towns and displacing hundreds of thousands of civilians. Despite a high-profile US-mediated accord signed earlier this month between DRC President Félix Tshisekedi and Rwandan President Paul Kagame under the oversight of US President Donald Trump, fighting has intensified, raising fears of a broader regional war and undermining international diplomatic initiatives.
The latest escalation centers on the rebels’ push into South Kivu province, with reports confirming the capture of the key border town of Uvira on December 10, 2025. M23 forces have since advanced further south along Lake Tanganyika, clashing with Congolese troops and allied militias. This offensive follows earlier 2025 gains, including the seizure of major cities like Goma in January and Bukavu in February, consolidating rebel control over vast mineral-rich territories in North and South Kivu.
Roots of the Conflict and Rwanda’s Role
The M23, or March 23 Movement, emerged in 2012 from mutinous Congolese Tutsi soldiers dissatisfied with the implementation of a 2009 peace deal. Revived in recent years, the group claims to protect Congolese Tutsis from Hutu militias like the FDLR (Democratic Forces for the Liberation of Rwanda), remnants linked to the 1994 Rwandan genocide.
However, overwhelming evidence from UN experts, the US, EU, and independent reports points to direct Rwandan military support, including thousands of Rwanda Defence Forces (RDF) troops fighting alongside M23, advanced weaponry, and logistical aid. Rwanda denies direct involvement, framing any actions as defensive against FDLR threats. Critics argue Kigali’s backing serves geopolitical and economic interests, including influence over DRC’s lucrative coltan, gold, and other mineral resources—M23 reportedly earns hundreds of thousands monthly from mining taxes.
The conflict traces back to the 1994 genocide’s spillover, when millions fled into DRC, fueling decades of instability involving over 100 armed groups. Eastern DRC remains one of the world’s worst humanitarian crises, with millions displaced and widespread atrocities.
The Faltering US-Brokered Peace Deal
On December 4, 2025, Presidents Tshisekedi and Kagame signed the Washington Accords in a ceremony hosted by President Trump, building on a June framework. The deal commits Rwanda to withdraw support for armed groups and DRC to neutralize FDLR threats, while promoting economic integration in the Great Lakes region.
Trump hailed it as a “historic” step toward prosperity, announcing bilateral US agreements for critical minerals access. However, M23—not a signatory—continues separate Qatar-mediated talks, and fighting has surged post-signing. Congolese officials accuse Rwanda of breaching commitments, with UN reports noting persistent RDF presence (estimated 5,000-7,000 troops) and advanced equipment like drones and missiles.
Analysts describe the accords as transactional, focused on minerals rather than root causes, with limited enforcement mechanisms. The offensive’s timing—days after the signing—has been called a “slap in the face” by regional leaders like Burundi’s president.
Humanitarian Toll and Regional Implications
The UN reports over 200,000 newly displaced since early December, compounding earlier waves that pushed millions into camps. At least 74 civilians killed in the Uvira push alone, with accusations of summary executions and sexual violence. Peacekeepers from MONUSCO and regional forces (including South African and Burundian troops) have suffered casualties, straining the UN mission.

Neighboring countries like Burundi and Uganda have bolstered deployments, fearing spillover. The conflict risks drawing in more actors, exacerbating ethnic tensions and resource exploitation.
As M23 entrenches parallel administrations in captured areas—restoring some order but imposing strict rules—the path to sustainable peace remains elusive. International calls for Rwanda’s withdrawal and genuine disarmament grow louder, but with rebels consolidating gains, eastern DRC faces prolonged instability.
