(Reuters) -Rwanda-backed M23 rebels pressed deeper into Congolese territory a day after Congo and Rwanda's presidents called for an immediate ceasefire, entering the outskirts of the town of Walikale late on Wednesday,

The Rwanda-backed rebels who captured key areas of Congo’s mineral-rich east say they have withdrawn from planned peace talks with the country’s government in Angola.

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.
