What recent territorial advances have M23 fighters and Rwandan soldiers made in the Democratic Republic of Congo?

After capturing Goma, the capital of North Kivu, M23 fighters and Rwandan soldiers have expanded their control into the neighboring province of South Kivu. They first advanced to the outskirts of Bukavu, the capital of South Kivu, before completely seizing the city on Sunday. This territorial expansion represents a significant escalation in the conflict, as the rebel forces have now captured two provincial capitals in eastern DRC. This advancement has serious implications for regional stability and has prompted international concern over human rights violations in the affected areas.
