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.
