From the UNICEF website:
The brutal, five-year old Syrian war has affected 80% of the country’s children — 8.4 million young livesshattered by violence, fear, displacement and death. The terrible conflict in besieged cities like Aleppo is increasing their suffering.
In response, UNICEF has helped mobilize the largest relief operation in history — providing safe water, nutrition, polio vaccinations, temporary schools and more. But these children’s needs are outgrowing our resources.
