Rwanda-backed rebels who captured eastern Congo's largest city said Thursday they want to take their fight to the far-off capital, Kinshasa, while Congo’s president called for a massive military mobilization to resist the rebellion and his defense minister rejected calls for talks.

What has been a slow-burn crisis in eastern DRC has again exploded into the open. Kagame appears to have calculated that a change of US administration is a good time to strike. A peace process mediated by Angola and sponsored by the US collapsed in the dying days of Joe Biden’s administration.

Rwanda's ally Uganda, unhappy about another rebel group in DR Congo that threatens its security, has also been accused of helping the M23 - with its officers also spotted at Tchanzu. The UN experts say Uganda has also supplied weapons, hosted rebel leaders and allowed cross-border movements of M23 fighters - accusations Kampala denies.
