Goma's Ndosho Hospital was treating 36 people for gunshot wounds on Tuesday.

The regional governor banned protests in the North Kivu regional capital after gunfire echoed through the streets as demonstrators barricaded roads with burning car tires, hurled stones and petrol bombs, and looted stores.
The violence erupted on Monday in Goma, when several hundred people stormed and vandalized the headquarters and a supply base of the MONUSCO.
They accuse the UN peacekeepers of failing to protect them from deadly attacks by the myriad armed groups active in the region.
