RESET: US blames Russia for Syria convoy attack; Moscow points to terrorists.

UN Secretary General Ban Ki-moon called the attack “sickening, savage and apparently deliberate.”

“Just when we think it cannot get any worse, the power of depravity sinks lower,” Ban told world leaders convening Tuesday at the UN General Assembly annual meeting.

Eighteen of the convoy’s 31 trucks were hit, the United Nations said. The convoy was due to deliver food and medical aid for some 78,000 people in eastern Aleppo, where an estimated 250,000 civilians are facing severe shortages as a result of a government siege.

Publicly, John Kerry sold the Syrian deal with Russia as a possible “turning point” in the five-year-old civil war. But privately, he “conceded to aides and friends that he believes it will not work,” even before it was implemented.
