South Sudanese military spokesman, Col. Philip Aguer, yesterday questioned the credibility of the report, saying it is not in South Sudanese culture to commit such atrocities and has called for a full investigation.
UNICEF Executive Director Anthony Lake said in a statement Wednesday that survivors reported that boys were castrated and left to bleed out, while girls were gang raped and killed.
Other children were thrown into burning buildings, he said, adding that the killings took place over three weeks in May in Unity state.

She said "these heinous crimes fly in the face of numerous commitments by all parties in South Sudan to stop violations against children."
Zerrougui called on the international community, especially the African Union and the Security Council, "to take concerted action to protect these children, who have grown up surrounded by violence and insecurity."
