Those "terrorists" are simply their version of the CIA's taliban/ISIS groups. Security institutions require a boogeyman for the people to not see they are the actuall terrorists.
Earlier in the day american-trained "terrorists" killed almost a hundred syrians, including several kids, but almost nobody in the west gives a shit about Syria.
