On September 20, in the village of Kanaker (province of Damascus) more than 500 fighters of the Islamic State and so-called moderate opposition laid down their arms,” Syrian agency SANA reports, adding that there is a video of ISIS militants yelling to government troops. The militants were said to be mercenaries from Iran, Turkey and Sudan. They received weapons from Saudi Arabia, Jordan and Lebanon. There are also many US-made weapons and heavy equipment.
Some of that equipment could have come from Iraq. When the Iraqis surrendered to ISIS and walked away leaving them with everything including over 2000 Humvees and automatic weapons. And there’s speculation that Obama wanted to create his own civil war in America by using ISIS.
