As many as 15 million children are caught up in violent conflicts around the globe, reports UNICEF. Globally, an estimated 230 million children currently live in countries and areas affected by armed conflicts.

“This has been a devastating year for millions of children,” said Anthony Lake, UNICEF Executive Director. “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. Never in recent memory have so many children been subjected to such unspeakable brutality.”

According to UNICEF, the sheer number of crises in 2014 meant that many were quickly forgotten or captured little attention. Protracted crises in countries like Afghanistan, the Democratic Republic of the Congo, Nigeria, Pakistan, Somalia, Sudan and Yemen, continued to claim even more young lives and futures. This year has also posed significant new threats to children’s health and well-being, most notably the Ebola outbreak in Guinea, Liberia, and Sierra Leone, which has left thousands of children orphaned and an estimated 5 million out of school.
