The M23 rebel group in Democratic Republic of Congo has seized the eastern town of Minova, a main supply route for the provincial capital Goma, a local governor and a rebel leader said on Tuesday as the army reported fighting on all fronts.

M23 rebels tightened their stranglehold over key trading routes to the city of Goma in eastern Democratic Republic of Congo after taking more towns Monday and Tuesday, Congo’s army said.
