Rwanda-backed M23 rebels on Monday pulled out of peace talks with the Democratic Republic of Congo's government less than 24 hours before the warring parties in eastern Congo's worst conflict in decades were due to convene in Angola.

The Rwanda-backed rebels who captured key areas of Congo’s mineral-rich east say they have withdrawn from planned peace talks with the country’s government in Angola.

M23 rebels said they were pulling out of talks with the government of the Democratic Republic of Congo because EU sanctions against Rwandan officials earlier in the day "undermined" negotiations.
