French United Nations Ambassador Francois Delattre said Sunday the barrage of Syrian government airstrikes that have pounded rebel-held areas of Aleppo since Friday amount to "war crimes" by the Bashar al-Assad regime and cannot be left unpunished. The "Security Council simply cannot accept such war crimes — yes, war crimes — to repeat again," Delattre argued, proposing "an immediate humanitarian truce in Aleppo and the Ghouta [a region of Syria near Damascus], 20 years after the siege of Sarajevo." Since Friday, more than 200 strikes have hit Aleppo, killing at least 100 people and leaving 2 million civilians without running water.
