Humanitarian groups are raising alarms about the devastating toll of this week’s escalated fighting in Aleppo, Syria. The UN describes it as the worst bombing yet in the country’s five-year-long civil war. Hospitals and food distribution points have been hit by airstrikes. Only a small number of doctors remain in the area, and they are not able to keep up with all the wounded. Aid groups say food and medical supplies are running dangerously low. A disproportionately high number of children are among the victims. Pope Francis renewed his calls for an end to the violence. In a meeting with aid groups, he said the perpetrators will be “accountable to God” for their action.
