2017 was Syria's deadliest year for children

910 children were killed in Syria in 2017, a 50% increase from 2016 and the most of any year since the war began in 2011, according to a new report from UNICEF. Conflict is now considered the leading cause of death for Syrian adolescents.

Why it matters: With no end in sight to the seven-year war, a humanitarian crisis in Syria continues to devolve into unspeakable tragedy. There are now more than 1 million Syrian children who have only ever known a lifetime of war.
