Negotiators for South Sudanese rebels have denied signing a power-sharing deal.

They said they only signed the document that set out how a ceasefire should be implemented at the ceremony in Ethiopia on Monday.

Thousands of people have been killed and more than a million people people driven from their homes because of the conflict, which started last December.

The BBC's Emmanuel Igunza reports.
