Some 200,000 girls and boys in eastern Ukraine are commuting to schools whose classroom walls are often riddled with bullets, and playgrounds scattered with metal remnants of war.

That’s according to the United Nations Children’s Fund, UNICEF, in a statement released on Friday, UN News reports.

“Children are learning in schools with bullet holes in the walls and sandbags in windows, bomb shelters in the basements and shrapnel in schoolyards,” said UNICEF’s Ukraine Representative, Giovanna Barberis.

“The education system in eastern Ukraine has been in the crossfire for more than four years. All sides of the conflict must respect international humanitarian law and ensure that schools are safe places for children to learn.”

At least 45 schools have been damaged or destroyed over the last 16 months; in addition to the more than 700 schools affected overall since the conflict began.

This means that classrooms are often close to military bases and security check points, increasing the risk that they may step on unexploded weapons of war, or be caught in crossfire.

“The children are extremely nervous of shelling and teachers try to calm them down, but it’s hard for them,” said Principal Elena Mihatskaya, whose secondary school in the town of Krasnohorivka has been shut down since last May due to massive damage caused by a shell. “It’s hard for kids to cope because they are nervous and stressed.”

This year, UNICEF has appealed for $23.6 million to provide urgent humanitarian assistance to children and families affected by the conflict in eastern Ukraine. To date, less than 15% of the appeal has been met.
