UNITED NATIONS, United States: UN Secretary General Ban Ki-moon condemned the attacks on Wednesday on the two largest hospitals in rebel-held parts of Syria’s Aleppo as “war crimes.” “Let us be clear. Those using ever more destructive weapons know exactly what they are doing. They know they are committing war crimes,” Ban told the Security Council. “Imagine the destruction. People with limbs blown off. Children in terrible pain with no relief,” he said. “Imagine a slaughterhouse. This is worse.”
