Democratic Republic of Congo President Felix Tshisekedi has long ruled out dialogue with the Rwanda-backed M23 rebels rampaging through eastern parts of his country, but a string of defeats and waning regional support have forced him think again.

Democratic Republic of Congo and M23 rebels will engage in direct negotiations in the coming days to end the conflict in the country’s mineral-rich east, according to the presidency of Angola, which will mediate the talks.

Congo's former President Joseph Kabila has initiated talks with opposition politicians about the country's political future as Rwanda-backed rebels seize territory in the east, five sources familiar with the outreach told Reuters.
