M23 insurgency in eastern Congo has intensified in January with the rebels seizing control of more territory than ever before, prompting the United Nations to warn of the risk of a broader regional war.

Congo has severed diplomatic ties with Rwanda amid intensifying M23 insurgency and ongoing battles. Allegations of Rwanda's involvement in the conflict have been denied by Rwanda, but tensions rose with the killing of a Congolese military governor.

Rwanda-backed M23 rebels in the Democratic Republic of Congo have taken over the key eastern trading town of Minova, according to various sources. The fall of the city puts the rebels within 40km (25 miles) of provincial capital, Goma, which lies close to the border with Rwanda.
