Syrian Civil War: who bombed aid convoy?

United States Secretary of State John Kerry lunched a blistering attack on the Russians and the Syrian regime at the United Nations Security council meeting today. He accused the Russians and the Syrian Regime of sabotaging the peace process by bombing the United Nations Aid convoy meant to deliver aid relief material to civilians in Allepo. Syria have been ravaged by a long civil war. he also said it will not be business as usual.  "How can people go sit at a table with a regime that bombs hospitals and drops chlorine gas again and again and again and again and again and acts with impunity," Kerry asked. "You're supposed to sit there and have happy talk in Geneva while the regime drops bombs?" Russia initially said that the strike was a necessary response to an alleged offensive by an al-Qaeda-linked terror group, Kerry said. Then Russia claimed they were bombing elsewhere, then that the aid convoy had been followed by militants with mortars, and then that the trucks caught fire. Watch the video here
