The Democratic Republic of Congo (DRC) has accused Rwanda of violating its sovereignty by sending troops to support armed groups.
The case, filed at the East African Court of Justice, highlights claims that Rwanda is backing rebel groups in eastern DRC.
The region has been unstable for years, with over 120 armed groups fighting for power, land, and resources.
Among the most powerful rebel groups is the M23, which the DRC, the United States, and France accuse Rwanda of sponsoring.
Rwanda has repeatedly denied these allegations, stating that it is not involved in the conflict.
Soldiers from the Armed Forces of the DRC (FARDC) are reportedly digging trenches at the frontline near the town of Kibirizi, which is under M23 control.
This legal battle adds to ongoing tensions in a region rich in mineral resources, plagued by violence and instability.
The outcome of the court proceedings remains to be seen as the situation in eastern DRC continues to evolve.
