“The dream we all shared for the children of this young country has become a nightmare,” said Justin Forsyth, UNICEF Deputy Executive Director said on Friday in a news release issued by the agency.

“At this precarious stage in South Sudan's short history, UNICEF fears that a further spike in child recruitment could be imminent,” he added.

The agency also warned that renewed conflict could put tens of thousands of children at an even greater risk. It further noted that despite widespread political commitment to end the practice children continue to be recruited and used by armed groups and forces.

According to estimates, some 16,000 children have been recruited by the armed groups and armed forces since the crisis first began in the country in December 2013.

The news release added that in 2015, UNICEF oversaw the release of 1,775 former child soldiers in what was one of the largest demobilizations of children ever. However, renewed fighting and recruitment in the world's youngest country risks undermining much of this progress, it noted.

The agency also highlighted increased grave violations in the country, noting that gender-based violence, already pervasive, has greatly intensified during the current crisis.

“Children continue to endure horrific ordeals,” stressed  Forsyth.

“Recent reports point to widespread sexual violence against girls and women. The systematic use of rape, sexual exploitation and abduction as a weapon of war in South Sudan must cease, together with the impunity for all perpetrators,” he said.

The UN agency further underscored that unconditional access for all humanitarian interventions in Juba and all other parts of the country is urgently needed to provide support, protection, and assistance to children and women across the country.

“Without a fully operational humanitarian sector, the consequences for children and their families will be catastrophic,” concluded  Forsyth, recently returning from a trip to the country's capital, Juba, and the northern town of Bentiu.
