The U.N. Security Council said Monday that it was concerned by "escalating violence" in the eastern Democratic Republic of the Congo, condemning in a statement the offensive launched this month by M23 rebels near Goma.
Clashes have intensified recently between the M23 — among the strongest of dozens of armed groups roaming the country's troubled east — and the Congolese army.
The DRC, the U.N. and Western countries say Rwanda is supporting the rebels in a bid to control vast mineral resources, an allegation Kigali denies.
Council members, who met Monday to discuss the issue, "reiterated their condemnation of all armed groups operating in the country. They expressed concern about the escalation of violence and a sustained tension in the region," according to a statement read by Guyana Ambassador Carolyn Rodrigues-Birkett.
Council members also specifically "condemned the M23 offensive," launched February 7, Rodrigues-Birkett said. "They reiterated their full support to the sovereignty, unity and territorial integrity of the DRC."
The M23 has seized vast swaths of North Kivu province since emerging from dormancy in late 2021, in an area wracked by violence for decades following regional wars in the 1990s.
The most recent flare-up has pushed thousands of civilians to flee the town of Sake, on the route toward Goma, capital of North Kivu province.
According to a U.N. document seen by AFP earlier Monday, the Rwandan army is using sophisticated weapons such as surface-to-air missiles to support M23.
A "suspected Rwandan Defense Force mobile surface-to-air missile" was fired at a U.N. observation drone last Wednesday without hitting it, the confidential report said.
U.N. forces have been in Congo for nearly 25 years, but stand accused of failing to protect civilians from armed groups.
The U.N. Security Council voted in December to accede to Kinshasa's demand for a pullout despite the volatile situation.
