US Secretary of State Marco Rubio has labeled Rwanda's actions in eastern Democratic Republic of Congo as a clear violation of the peace deal brokered by Donald Trump just last week. In a social media post, he announced that the US would take action to uphold the promises made at the presidential level.

Trump hailed the agreement signed in Washington between DR Congo's President Félix Tshisekedi and Rwanda's President Paul Kagame as historic. However, the M23 rebel group declared it has fully liberated the key city of Uvira, which many Western powers claim is backed by Rwanda.

The latest fighting jeopardizes an already complicated conflict, with analysts pointing out that the timing of the M23's offensive seems to aim at negotiating leverage while simultaneously undermining confidence in the US diplomatic efforts.

Uvira, lying near the Burundian capital, is of strategic importance for its proximity to multiple troop movements, as the M23's capture impacts not only DR Congo but also presents repercussions for Burundi, which has a history of conflict with Rwanda.

The M23's offensive further complicates the region's precarious peace process, especially with parallel negotiations led by Qatar. Observers note that the situation complicates Tshisekedi's position and presents severe challenges to regional stability.
