Officials and residents say Rwanda-backed rebels have gained ground in eastern Congo despite the unilateral ceasefire they declared earlier this week, taking control of a town 100 kilometers (60 miles) from the provincial capital of Bukavu.

A major offensive by Rwandan-backed M23 rebels in east Democratic Republic of Congo appeared to have stalled on Saturday after the army took back some ground, two civil society sources and a local official said.

The group has made dramatic advances in Congo’s North Kivu province since re-emerging as a force in late 2021. It has repeatedly denied receiving support from Rwanda. And the government in Kigali equivocates about its support for the rebels.

The rebels continued advances in eastern Congo despite their own announcement of a cease-fire. The U.N. secretary-general called for them to lay down their guns and agree to mediation.

Rwandan-backed M23 rebels in Democratic Republic of Congo are seeking to advance south towards Bukavu, the capital of South Kivu province, in an attempt to expand their area of control in the country's east after capturing the city of Goma.

Rwanda-backed rebels who have captured eastern Congo’s largest city say they plan to take their rebellion to the capital and seek to gain political power.
