Children in Juba urged leaders to find a peaceful solution to ongoing conflict in South Sudan.
In a statement, UNICEF said children used drama, songs, poems and exhibition of art about effects of conflict to address their leaders.
A quarter million of children under the age of five would suffer from severe acute malnutrition in 2014 and that 50 thousand of them would die unless they get access to treatment.
South Sudan UNICEF Representative Jonathan Veitch said children are suffering unthinkable, multiple tragedies and that hundreds of thousands of them lost homes, parents and others recruited by armed groups.
She added that children are at risk of disease and famine.
Child Welfare Director Celina Peter underlined the need for peace for children to have access to education.
