Kinshasa, M23 rebels fail to sign peace deal

The Democratic Republic of Congo's government and defeated M23 rebels fail to sign a peace deal aimed at ending their long-running conflict. Meanwhile, Somali refugees in Kenya must only return home voluntarily - that's the message from the UN in a deal set to ease the fears of over half a million refugees. Finally, Chad's president presents UNESCO with the cast of a Toumaï skull. The mould is of the oldest hominid, said to be about 7 million years old.
