The U.N.'s top human rights body agreed Friday to a text presented by Congo that “firmly condemns” support of rebel fighters by neighboring Rwanda in eastern Congo. It also orders the creation of a team of experts to examine rights violations in the region.

Goma remains “under occupation” by Congo’s M23 rebels and the ceasefire they announced has been broken as their forces engage in heavy fighting along the main route to South Kivu’s main city Bukavu.

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.
