The United Nations children's agency UNICEF declared 2014 a devastating year for children with as many as 15 million caught in conflicts in Central African Republic, Iraq, South Sudan, Syria, Ukraine and the Palestinian territories.
UNICEF Executive Director Anthony Lake said the high number of crises meant many of them were quickly forgotten or failed to capture global headlines, such as in Afghanistan, Democratic Republic of Congo, Nigeria, Pakistan, Somalia, Sudan and Yemen.
Globally, UNICEF said some 230 million children were living in countries and regions affected by armed conflict.
"Children have been killed while studying in the classroom and while sleeping in their beds; they have been orphaned, kidnapped, tortured, recruited, raped and even sold as slaves," Lake said in a statement. "Never in recent memory have so many children been subjected to such unspeakable brutality."
Significant threats also emerged to children's health and well-being like the deadly outbreak of Ebola in the West African countries Guinea, Liberia and Sierra Leone, which has left thousands orphaned and some 5 million out of school.
"Violence and trauma do more than harm individual children - they undermine the strength of societies," Lake said.
