M23 rebels have captured Bunagana border on the side of the Democratic Republic of Congo (DRC) forcing over 150 government soldiers to flee into Uganda.
The FARDC soldiers have surrendered to Ugandan authorities at Bunagana border.
This follows renewed fighting near Bunagana border in Rutshuru territory, which started on Friday.

While at the border, they handed over all the guns to Ugandan security and were escorted to the nearby Uganda Peoples Defense Forces (UPDF) barracks in Kabaya, Bunagana.
