In a rare access granted to BBC, rebels from the M23 in the DR Congo showcased a mine that plays a crucial role in powering mobile phones. Meanwhile, the United Nations has accused Rwanda of utilizing the M23 insurgents to gain access to minerals in the DR Congo. Recent UN reports have established ties between a Rwandan-Russian firm and the illicit trade of Congolese coltan, indicating that this operation is funding the M23 conflict and perpetuating instability in the region.
