INTERVIEW: former US Ambassador Herman Cohen explains the current conflict in DRC

There are fears for thousands of people across the eastern Democratic Republic of the Congo, after the M23 rebel group took the town of Nyanzale, killing at least 15 people. The town is just 30 kilometres from the provincial capital Goma, with analysts saying M23 could be emboldened to advance further into government-held territory. The United States says the group has the backing of the DRC's neighbour Rwanda. To understand more about the conflict, and the significance of the rebel group's advance, Tys Occhiuzzi spoke with Herman Cohen, a former US Ambassador and Assistant Secretary of State to President George HW Bush.
