The United Nations Security Council has warned that the Democratic Republic of Congo is at risk of descending into violence. According to UN envoy Maman Sidikou, all parties in the political impasse appear willing to use extreme measures as a means to an end. Protests broke out last month after the presidential election -- scheduled for November -- was postponed indefinitely. Dozens of people were killed. Opposition leaders have accused President Joseph Kabila of trying to cling to power. The constitution bars Kabila from running for another term. He's ruled the DRC since 2001.
