The United Kingdom has cautioned Rwanda that its involvement in the escalating conflict in the Democratic Republic of Congo (DRC) could put at risk the over $1 billion in global aid it receives annually.

On Monday, M23 rebels—allegedly backed by Rwanda—captured Goma, a major city in eastern DRC with a population of two million. Despite international calls for a ceasefire, the rebels extended their offensive on Wednesday.

According to the DRC government, as well as the United States and other Western nations, Rwandan forces have provided military support to M23 rebels. However, Rwanda has repeatedly denied any involvement.

Speaking in the UK Parliament on Tuesday, British Foreign Secretary David Lammy emphasized that Rwanda's aid package—comprising around £32 million ($39.8 million) in bilateral UK assistance—is at risk if it violates its neighbor’s sovereignty.

"Any nation that challenges the territorial integrity of another will face consequences," Lammy stated. "Just as we stand against such actions in Europe, we must uphold the same principles worldwide."

This latest conflict marks the most significant escalation in eastern Congo since 2012. The violence stems from historical tensions linked to the 1994 Rwandan genocide, alongside ongoing struggles over the region's vast mineral resources
