BAALBEK, Lebanon — This week, as the international community marked the annual World Refugee Day, the Syrian crisis has entered its sixth year. Nearly 5 million Syrians are taking refuge all across the Middle East while others, including many Syrian children, continue to risk their lives for a chance to reach Europe’s doorsteps.

In 2014, only three years into the conflict, UNICEF reported that “Syria is now one of the most dangerous places on earth to be a child.” Nearly half of the war-torn country is displaced. According to the United Nations, children make up almost half of the refugee and the internally displaced populations. Life expectancy has fallen by 20 years.

Today, the mass migration of Syrian refugees poses an even more urgent need for humanitarian aid and physiological and mental health relief — particularly among the crisis’ most innocent victims, Syria’s children. They may have survived six years of war, but many now carry enduring mental scars from the conflict.

“My friend was stabbed by another boy. I don’t want to be like them,” Ahmad, who lives among other vulnerable Palestinian and Syrian refugees in Lebanon, told Al-Monitor.
