South Sudan President Salva Kiir has set out a series of conditions for his former vice president to be granted amnesty.

President Kiir’s bitter rival, former first vice president Riek Machar, remains in exile.

Machar fled the capital, Juba, earlier this year when fighting broke out between his forces and those loyal to the president.

Kiir maintains that he is committed to bringing peace to the world’s youngest nation.

But to achieve this, he says, Machar must also denounce violence.

The president says he is working on an amnesty deal for his former rival, but says Machar won’t benefit from it unless he orders his supporters to lay down their weapons.
