Rwandan President Paul Kagame has told CNN he doesn’t know if his country’s troops are in the east of the Democratic Republic of Congo (DRC), where fighting between the M23 armed group and Congolese soldiers has killed more than 700 people and injured thousands in recent days.

The city of 2 million people is at the heart of a region home to trillions of dollars in mineral wealth and remains in rebel control.

Kenya has announced a virtual crisis summit, but Congolese state media says President Felix Tshisekedi will not attend.

The Congolese government, alongside U.N. officials and Western powers, including the United States, has accused neighbouring Rwanda of exacerbating the conflict by deploying thousands of troops and heavy weaponry in support of M23.
