U.N Secretary General "Ban Ki-moon" reiterated a call for perpetrators of violence in South Sudan to be brought to justice reminding those responsible that they will be held accountable. He calls on the government and all concerned to ensure the rights and security of civilians are protected".
Ban's spokesman said in a statement "all violence, attacks and human rights abuses must end immediately ".
The government on Saturday meanwhile accused sacked former vice president and rebel leader "Riek Machar" of recruiting up to 25,000 young men of the Nuer tribe in eastern Jonglei state.
But rebel spokesman Moses Ruai Lat denied the allegation, telling AFP that Machar was "not mobilising his tribe", South Sudan's second biggest ethnic group, stressing that those young people were regular soldiers turning their back on the government and had not been drafted by Machar.
The accusations came as East African and Horn of Africa peace brokers set a Tuesday deadline for Kiir and Machar to start face-to-face talks and stop two weeks of fighting.
