The United Nations said that the civil war in South Sudan has forced more than two million children to flee their homes, Sky news reported Monday.

"No refugee crisis today worries me more than South Sudan, Valentin Tapsoba, the Africa chief for the UN refugee agency UNHCR, said in a statement.

UNHCR and the UN children's agency UNICEF said in a country of 12 million people, nearly three in every four children do not go to school. 

More than 1 million children have fled outside South Sudan while another 1 million are internally displaced, they added.

The civil war in the oil-producing country began two years after it won independence from neighboring Sudan, when President Salva Kiir fired his deputy in 2013.
