In Syria, a pair of suicide bomb blasts tore through buses transporting Iraqis to a cemetery near Damascus Saturday, killing at least 74 people and injuring scores of others. Most of the dead were Shia pilgrims. A Sunni rebel alliance called the Fatah al-Sham Front, which was formerly allied with al-Qaeda, claimed responsibility. The violence came as the United Nations Children’s Fund reported 2016 was the worst year yet in Syria’s 6-year-old civil war. UNICEF found child deaths jumped at least 20 percent over the prior year, while the rate of child conscription doubled.
