From part 2
Within a day, the combined jihadi forces had broken through the lines of the Syrian Army. Shortly after, Regiment 111 was fully under jihadi control. They found large stocks of weapons, ammunition and, to their surprise, chemical agents. They were, according to Abu Ahmad, mainly barrels filled with chlorine, sarin, and mustard gas.
What followed was the distribution of the war spoils. Everybody took some ammunition and weapons. But only the Nusra Front seized the chemical weapons. Abu Ahmad watched as the al Qaeda affiliate called in 10 large cargo trucks, loaded 15 containers with chlorine and sarin gas, and drove them away to an unknown destination. He did not see what happened to the mustard gas.
From part 3
On Jan. 20, 2014, the split between Syria’s two jihadi powerhouses became final. In Kafar Joum, ISIS prepared a convoy of over 200 vehicles. The cars and trucks were packed with fighters, family members, weapons, and foreign hostages. In the convoy, Abu Ahmad noticed three of the 15 chemical containers he saw Nusra capture from Regiment 111.
Then, the huge ISIS train of steel and bodies roared off to the east, toward the city of Raqqa.
So.... with so much propaganda/ information overload floating around, who actually pulled the trigger
