At leat 652 children in Syria died during 2016 as a result of the ongoing violence in the country, UNICEF said in a press release Sunday, making it the worst year yet for Syrian children since formal verification of child casualties began in 2014. The death toll was a 20 percent increase over 2015.

UNICEF found the number of children recruited to participate in the war doubled since 2015; more than 850 children were recruited in 2016 in various capacities such as executioners, suicide bombers etc and about 255 children were killed in their schools. All in all, about 6 million children in Syria depend on humanitarian assistance now, an increase of over 12 times since 2012. Millions more have been displaced and are now living as refugees in Turkey, Lebanon, Jordan, Egypt and Iraq.

“The depth of suffering is unprecedented. Millions of children in Syria come under attack on a daily basis, their lives turned upside down… Each and every child is scarred for life with horrific consequences on their health, well-being and future,” Geert Cappelaere, UNICEF regional director for the Middle East and North Africa, said in the press release.

Another recently released report by Save the Children, called Invisible Wounds, found that children in Syria are suffering from “staggering levels” of ‘toxic stress” that can cause permanent and irreversible damage. More than 70 percent of children interviewed reportedly displayed symptoms of post-traumatic stress disorder. Loss of speech, associated speech impediments, increased aggression and resorting to substance abuse as a coping mechanism, were things commonly observed among Syrian children.

But despite the grim horrors surrounding them, Cappelaere said there were still several remarkable stories of children who aspire to learn and continue to hope for a better future. For instance, Darsy (12), now a refugee in Turkey said: “I want to be a surgeon to help the sick and injured people of Syria. I dream of a Syria without a war so we can go home. I dream of a world without any wars.”

“We continue to witness the courage of Syria’s children. Many have crossed frontlines just to sit for school exams. They insist on learning, including in underground schools. There is so much more we can and should do to turn the tide for Syria’s children,” Cappelaere emphasized.
