Armed Groups

The United Nations Security Council (UNSC) has condemned Rwanda for backing a rebel offensive in eastern Democratic Republic of the Congo and urged it to withdraw its forces and stop supporting the M23 armed group.

The UNSC unanimously adopted the resolution on Friday, and also extended the UN peacekeeping mission in the DRC, known as MONUSCO, for a year. This came despite Rwanda’s repeated denials – contrary to overwhelming evidence – of involvement in a conflict that has intensified as a United States-brokered peace deal unravels.

The UNSC said M23’s seizure of the strategic city of Uvira “risks destabilizing the whole region, gravely endangers civilian populations and imperils ongoing peace efforts”.

“M23 must immediately withdraw at least 75km (47 miles) from Uvira and return to compliance with all of its obligations undertaken in the Framework Agreement,” said Jennifer Locetta, a US representative to the UN.

M23 captured Uvira in the South Kivu Province on December 10, less than a week after the DRC and Rwandan presidents met US President Donald Trump in Washington and committed to a peace agreement.

“It is an amazing day: great day for Africa, great day for the world and for these two countries. And they have so much to be proud of,” Trump crowed, as fighting quickly undermined the White House spectacle.

One Uvira resident, Feza Mariam, told Al Jazeera in recent days: “We don’t know anything about the political process they are talking about.

“The only thing we need is peace. Anyone able to provide us with peace is welcome here. For the rest, we as citizens, we don’t care about it.”

The M23 group claimed on Wednesday it was withdrawing from the city following international backlash, but the DRC government dismissed this as a “staged” pullback, saying M23 forces remain deployed there.

US Secretary of State Marco Rubio acknowledged on Friday that commitments under the Washington accord were “not being met” but said his government had now signed agreements it could “hold people to”.

The US earlier warned it would use available tools against those undermining the peace deal, with US officials estimating between 5,000 and 7,000 Rwandan soldiers were operating in eastern DRC as of early December.

The US had previously sanctioned Rwandan cabinet ministers earlier this year, and the DRC later led calls to expand those sanctions after the seizure of Uvira.

The fighting has triggered a major humanitarian emergency, with more than 84,000 people fleeing into Burundi since early December, according to the UN refugee agency, which said the country has reached a “critical point” as refugees arrive exhausted and traumatised. They join approximately 200,000 others who had already sought refuge in the country.

Regional officials say more than 400 civilians have been killed in recent violence in the city.

The seizure of Uvira, located directly across Lake Tanganyika from Burundi’s largest city, Bujumbura, has raised fears of broader regional spillover. The city was the last major foothold in South Kivu for the DRC government and the Wazalendo, which are DRC-allied militias, after M23 captured the provincial capital, Bukavu, in February.

Rwanda has consistently denied backing M23, despite assessments by UN experts and the international community. In a February interview with CNN, Rwandan President Paul Kagame said he did not know whether his country’s troops were in the DRC, despite being commander-in-chief of the armed forces.

Rwanda implicitly acknowledged a presence in eastern DRC in February 2024, when it rejected a US call to withdraw troops and surface-to-air missile systems, saying it had adjusted its posture for self-defence.

Rwanda maintains that its security concerns are driven by the presence of the Democratic Forces for the Liberation of Rwanda, a militia composed largely of Hutus who fled to the DRC after participating in the 1994 genocide that killed approximately 800,000 Tutsis and moderate Hutus.

Kigali views the group as an existential threat and accuses the DRC government of supporting it.

The broader conflict in the mineral-rich eastern DRC, where more than 100 armed groups operate, has displaced more than seven million people, creating one of the world’s worst humanitarian crises.

Congolese refugees have recounted harrowing scenes of death and family separation as they fled intensified fighting in the eastern Democratic Republic of the Congo (DRC), where Rwanda-backed M23 rebels captured a strategic city despite a recent United States-brokered peace agreement.

M23 has cemented control over Uvira, a key lakeside city in DRC’s South Kivu province that it seized on Wednesday, despite a peace accord that President Donald Trump had called “historic” when signed in Washington just one week earlier.

Al Jazeera, which is the first international broadcaster to gain access to the city since M23’s takeover, saw residents tentatively returning home after days of violence, amid a heavy presence of rebel fighters on Friday.

The day before, M23 fighters combed the streets to flush out remaining Congolese forces and allied militias – known as “Wazalendo” – after taking over key parts of the city.

Meanwhile, at Nyarushishi refugee camp in Rwanda’s Rusizi district, Akilimali Mirindi told the AFP news agency she fled South Kivu with just three of her 10 children after bombs destroyed her home near the border.

“I don’t know what happened to the other seven, or their father,” the 40-year-old said, describing corpses scattered along escape routes as about 1,000 people reached the camp following renewed clashes this month.

Regional officials said more than 413 civilians have been killed since fighting escalated in early December, with women and children among the dead.

The offensive has displaced about 200,000 people, and threatens to drag neighbouring Burundi deeper into a conflict that has already uprooted more than seven million across eastern DRC, according to United Nations figures.

Uvira sits on Lake Tanganyika’s northern shore, directly across from Burundi’s largest city, and serves as South Kivu’s interim government headquarters after M23 seized the provincial capital, Bukavu, in February.

Al Jazeera correspondent Alain Uaykani, who gained access to the city on Friday, reported a tenuous calm and the heavy presence of M23 soldiers but described harrowing scenes on the journey there.

“Here in Uvira, we have seen different groups of the Red Cross with their equipment, collecting bodies, and conducting burials across the road,” Uaykani said.

He added that the Al Jazeera crew saw abandoned military trucks destroyed along the road to Uvira, and the remains of people who were killed.

Residents who fled Uvira told AFP of bombardment from multiple directions as M23 fighters battled Congolese forces and their Burundian allies around the port city.

“Bombs were raining down on us from different directions,” Thomas Mutabazi, 67, told AFP at the refugee camp. “We had to leave our families and our fields.”

‘Even children were dying’

Refugee Jeanette Bendereza had already escaped to Burundi once this year during an earlier M23 push in February, only to return to DRC when authorities said peace had been restored. “We found M23 in charge,” she said.

When violence erupted again, she ran with four children as “bombs started falling from Burundian fighters”, losing her phone and contact with her husband in the chaos.

Another refugee, Olinabangi Kayibanda, witnessed a pregnant neighbour killed alongside her two children when their house was bombed. “Even children were dying, so we decided to flee,” the 56-year-old told an AFP reporter.

M23 spokesperson Lawrence Kanyuka announced on Wednesday that Uvira had been “fully liberated” and urged residents to return home.

Fighting had already resumed even as Trump last week hosted Congolese President Felix Tshisekedi and his Rwandan counterpart Paul Kagame at a widely attended signing ceremony.

The December 4 Washington agreement obliged Rwanda to cease supporting armed groups, though the M23 was not party to those negotiations and is instead involved in separate Qatar-mediated talks with Kinshasa.

DRC’s government accused Rwanda of deploying special forces and foreign mercenaries to Uvira “in clear violation” of both the Washington and earlier Doha agreements.

The US embassy in Kinshasa urged Rwandan forces to withdraw, while Congolese Foreign Minister Therese Kayikwamba Wagner called for Washington to impose sanctions, saying condemnation alone was insufficient.

Rwanda denies backing M23 and blames Congolese and Burundian forces for ceasefire violations.

In a statement on Thursday, President Kagame claimed that more than 20,000 Burundian soldiers were operating across multiple Congolese locations and accused them of shelling civilians in Minembwe.

UN Secretary-General Antonio Guterres warned the escalation “increases the risk of a broader regional conflagration” and called for an immediate cessation of hostilities.
