The civil war in South Sudan has forced more than two million children to flee their homes, according to two UN agencies. Children make up 62 percent of the more than 1.8 million South Sudanese refugees who have arrived mainly in Uganda, Kenya, Ethiopia and Sudan, say the UN children's fund, UNICEF, and the refugee agency, UNHCR. More than a million children have, meanwhile, been internally displaced. "No refugee crisis today worries me more than South Sudan," said Valentin Tapsoba, Africa director for UNHCR.
South Sudan has been riven by a civil conflict since a split between President Salva Kiir and his former deputy, Riek Machar, escalated in December 2013. Tens of thousands have been killed and 3.5 million displaced. About 100,000 people are facing a famine and a million are on the brink of famine. The UN announcements came on the same day that a monitoring group warned a third South Sudanese county is at risk of famine.
