The U.N. says Rwanda-backed rebels are expanding their presence in eastern Congo after capturing the region's major city.

The United Nations expressed deep concern at reports of M23 rebels and Rwandan troops advancing south towards the Congolese city of Bukavu on Thursday, as the militants sought also to assert their control over east Congo's largest city Goma.

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.
