What is causing concerns about the potential breakup of the Democratic Republic of Congo?

The Democratic Republic of Congo faces potential breakup due to the rapid advancement of Rwanda-backed M23 rebels in the mineral-rich eastern region. These rebels have captured key cities like Bukavu and Goma with minimal resistance from Congolese Armed Forces, prompting the African Union to issue stark warnings about national disintegration if the situation persists. The conflict has deep historical roots dating back to the Rwandan genocide in the 1990s and has now escalated into a regional crisis. The African Union's Peace and Security Commissioner has called for the immediate removal of M23 forces from captured territories and urged all parties to engage in mediation to prevent further territorial losses and potential balkanization of the country.
