After weeks of intense fighting in the eastern Democratic Republic of the Congo, M23 rebels say they have taken control of parts of Goma, one of the main cities in the mineral-rich region. The Congolese government, on Monday, rejected an ultimatum to open talks with M23. This came after the rebels gave the government 24 hours to withdraw troops and open direct negotiations before they said they would advance on Goma. So, why does the DR Congo government refuse to hold talks with the rebel soldiers? And is military action really the answer to this conflict?
