The convoy's deadly fate Monday capped a rapid unraveling of week-old truce efforts, brokered by the United States and Russia. The plan intended to open routes to aid thousands of besieged Syrians and possibly spur greater military cooperation between Moscow and Washington to battle militants such as the Islamic State.
What was left Tuesday was a return of shelling and airstrikes in places that had hoped to receive critical food and medicine — including embattled Aleppo — and angry denials from Russia that it was responsible for targeting the aid convoy.
The International Committee of the Red Cross called Monday's attack a "flagrant violation of international law," and the U.N. said it could amount to a war crime. The convoy was carrying U.N. supplies distributed by the Syrian Arab Red Crescent in the village of Big Orem near Aleppo.
