Eastern DRC has been beset by conflict for years, with M23 among more than 100 armed groups vying for a foothold in the mineral-rich area near the border with Rwanda. Some have been accused of carrying out mass killings.
There's been an upsurge in fighting in recent weeks between M23 rebels and army forces, and it comes as the United Nations plans to withdraw peacekeepers from the region by the end of the year.
Tensions are also rising between DRCand Rwanda, with them blaming each other for supporting various armed groups. Kinshasa accuses Kigali of backing M23.
This weekend, the U.S. State Department condemned what it called the “worsening violence." A group of aid agencies has estimated that 1 million people have already been displaced by fighting in the last three months.
Who are M23?
The March 23 Movement, or M23, is a rebel military group mainly made up of ethnic Tutsis that broke away from the DRC army just over a decade ago. They staged a large offensive in 2012 and took over the provincial capital of Goma near the border with Rwanda, the same city they are threatening again.
The conflict has regional complications, with neighboring Rwanda also accused by the U.S. and U.N. experts of giving military aid to M23. Rwanda denies that but effectively admitted on Monday that it has troops and missile systems in eastern DRC. Rwanda said that is to safeguard its own security because of what it claims is a buildup of DRC army forces near the border. Rwanda has rejected calls from the U.S. to withdraw.
There are also ties to the Rwandan genocide of 30 years ago, with M23 and Rwanda saying separately that they are fighting a threat from a DRC rebel group that is connected to the DRC army and partly made up of ethnic Hutus who were perpetrators of the 1994 genocide.
DRC-Rwanda Tensions
Relations between DRC and its eastern neighbor have been fraught for decades. Hundreds of thousands of Rwandan Hutu refugees had fled to DRC, then Zaire, in the aftermath of the 1994 Rwandan genocide. Among them were soldiers and militiamen responsible for the slaughter of 800,000 minority Tutsis and moderate Hutus.
Two years after the genocide, Rwanda and Uganda invaded eastern DRC to try and root out what remained of those genocide perpetrators, which led to the toppling of then DRC President Mobutu Sese Seko.
Tensions between DRC and Rwanda escalated in 2021 with the resurgence of M23 attacks on DRC soldiers after nearly a decade of relative inactivity due to a 2013 peace deal. The presence of so many armed groups is believed to be connected to illegal mining, with eastern DRC rich in gold and other minerals.
What's Happened in Recent Weeks
M23 launched new attacks late last year and has ramped them up in recent weeks. The group is now threatening to take the key town of Sake, about 27 kilometers (16 miles) west of Goma. That could cause food and aid supplies to be cut off from Goma, which had a population of around 600,000 a few years ago, but now holds more than 2 million people, according to aid agencies, as people flee violence in surrounding towns and villages.
The advance of rebels on Sake “poses an imminent threat to the entire aid system” in eastern DRC, the Norwegian Refugee Council said. It said 135,000 people were displaced in just five days in early February.
The violence has also sparked protests from the capital, Kinshasa, to Goma, with angry demonstrators saying the international community is not doing enough to push back against M23 and not taking a hard enough stance against Rwanda.
What's at Stake?
The new fighting could lead to an escalation of regional tensions and involve more countries. As the U.N. winds down its 25-year peacekeeping mission in eastern DRC, a multi-national force under the southern African regional bloc is set to step in. That force will include soldiers from regional power South Africa, Malawi and Tanzania. They will help the DRC army forces, but it might put them in direct conflict with Rwanda.
There's also the humanitarian cost. The International NGO Forum in Congo, a group of non-governmental organizations working in the region, said the escalation in fighting has involved artillery attacks on civilian settlements, causing a heavy toll and forcing many health and aid workers to withdraw.
Eastern DRC already had one of the world's worst humanitarian crises, with nearly six million people previously displaced because of conflict, according to the U.N. Refugee Agency.
There are concerns a new disaster could largely go unnoticed because of the attention on the war in Gaza and Russia's invasion of Ukraine.
