Violence in Syria took a horrible toll on the country's children last year, the United Nations' children's agency says, with the civil war blamed for killing at least 652 children — 255 of whom were either in or near a school.In another unsettling trend, 851 children were recruited and used in the conflict in 2016 — double the figure who were recruited in 2015, UNICEF says. The agency says that children's deaths rose 20 percent and injuries rose by 25 percent.The agency's report, released Monday, is titled "Hitting Rock Bottom.""The depth of suffering is unprecedented. Millions of children in Syria come under attack on a daily basis, their lives turned upside down," UNICEF Regional Director for the Middle East and North Africa Geert Cappelaere said in a statement sent from Homs, Syria. "Each and every child is scarred for life with horrific consequences on their health, well-being and future."A third of Syria's schools are now unusable — either because they were attacked or because they're being used as either shelters or military posts, UNICEF says. The agency says all sides of the conflict have also used water as a weapon, citing 30 deliberate water-service cutoffs in cities such as Aleppo, Damascus, Hama, Raqqa and Daraa.Inside Syria, UNICEF says, nearly 6 million children now rely on humanitarian aid; an additional 2.3 million are living as refugees in neighboring countries. Many of those children have missed years of education or have never been to school, the agency says, citing makeshift facilities at refugee camps and parents' fears for their children's safety in areas that have been under siege.Multiple rounds of peace talks have failed to end Syria's civil war. Representatives of government and opposition groups are preparing for new discussions in Kazakhstan.From Istanbul, NPR's Peter Kenyon reports:
