#47. Russian bombers are big and can be spotted/photographed or Iphoned from the ground and sent out to the world.
Smaller fighter planes or helicopters are the best way to deliver rockets and Fuel Bombs and toxic gas.
Could have been the Syrian Army, the Russians (who don’t give a shit what the world thinks), Al Qaeda’s own supplies, ISIS supplies, etc.
Everyone of these have something to gain from killing rebels and their families, including other rebels, so it’s a crap shoot right now as to who did it.
Last year it was Syrian army fighter jets that delivered the gas. They were tracked loading, taking off, delivering and landing back at the airfield.
