GOMA, Congo (AP) — Dozens of Congolese demonstrated in the provincial capital of Goma on Thursday against what they described as the impotence of the country’s armed forces, which allowed a rebel group to overrun the city a little over two weeks ago. They also decried the passivity of United Nations peacekeepers, who did little to stop the fighters saying it was not within their mandate.

Goma, a city of about 1 million people and a major trading hub for minerals extracted from Congo’s lucrative mines, fell to a Rwandan-backed rebel group on Nov. 20. It took days of negotiations, intense international pressure, and the hammer of United Nations sanctions for the thousands of fighters for M23 to finally withdraw from the regional capital this weekend.
