Warring rebels and militias in eastern Democratic Republic of Congo signed a ceasefire deal on Wednesday aimed at ending conflict at the heart of one of the world’s most deadly humanitarian catastrophes.

The peace pact in the eastern town of Goma was signed by Tutsi rebels loyal to renegade Gen Laurent Nkunda, the government of Joseph Kabila, president, and several militia and armed groups from Congo’s North and South Kivu provinces.
