South Sudan rebels 'flaunt weapons' in video

Even before South Sudan declares its independence next week, it is already fighting at least half a dozen rebel movements.
On a video recording obtained by the BBC, hundreds of fighters from Peter Gadet's South Sudan Liberation Army (SSLA) jog rhythmically in a wide circle, singing and flaunting their new weapons.
The apparently joyous scenes in the video clash violently with a bloody reality: the rebel groups have fought on numerous occasions with the southern army, and represent a great threat to the stability of the new state.
