Rwanda-backed rebels were quickly expanding their presence in eastern Congo after capturing Goma, the region's major city, the U.N. said Friday, also expressing concerns over executions it learned were carried out by the rebels following a major escalation of their yearslong rebellion.

Rwandan-backed M23 rebels asserted their control over east Congo's largest city Goma on Thursday by calling on residents to resume normal life, even as the group clashed with Congolese troops as they tried to take more territory.

Kenyan President William Ruto, the East African Community (EAC) chair, convened a virtual summit on 29 January to discuss the worsening security situation – which Tshisekedi skipped. In his absence, the summit “strongly urged” him to engage directly in talks with the M23.
