M23 rebels claim control of DR Congo's coltan mining town of Rubaya

 M23 rebels in eastern Democratic Republic of Congo have taken control of Rubaya, a key mining town for the smartphone mineral coltan, following days of intense fighting, a rebel spokesman said.

Congo's east has been plagued by violence since the 1990s, killing millions as struggles over national identity, ethnicity, and resources saw neighbouring countries invade and a myriad of armed groups spring up.
