The President of South Sudan Salva Kiir has ruled out a power-sharing agreement with the rebel leader Riek Machar to try to end ethnic violence that's left thousands dead.

These men have rebelled. If you want power, you don't rebel. You go through the process. When I came here, I did not come through a military coup. I came because I was elected by the people. Elections are coming in 2015. Why did he not wait, so that he goes through that same process.

A religious leader in the Democratic Republic of Congo has told the BBC that his followers carried out the attacks in the capital Kinshasa on the airport, the national broadcasting station and a military base. The self-proclaimed prophet Joseph Mukungubila who is a critic of President Kabila said the violence was in response to government harassment. Richard Hamilton reports.

Joseph Mukungubila who calls himself the "eternal prophet" ran unsuccessfully against Joseph Kabila for the presidency back in 2006. Since then, he says, he and his followers have suffered frequent harassment. He told the BBC that the final stroke came when security forces beat up supporters who were distributing an open letter from him against the president. He said Monday's attacks were in reaction to this government repression. It looks as if the security forces opened fire on many youths armed just with machetes and sticks, leaving corpses on the streets of Kinshasa.
