Jan. 31 (UPI) -- The Democratic Republic of Congo's foreign minister on Friday accused Rwanda of illegally occupying part of its territory, after the M23 rebel group captured the eastern Congolese city of Goma. Foreign Minister Therese Kayikwamba Wagner made the claim to the BBC , saying that she believed Rwanda was attempting to orchestrate a regime change in the DRC as international leaders had failed to hold Rwandan President Paul Kagame accountable for violations of international law.
