At Aleppo, the dead students were disproportionate Shia/Alawite, Christian or Druze. Since the crisis began Sunni students were discouraged from attending.
There is no doubt about who killed those who were allowed to attend and how. The only question is why? The attack clearly came from air-to-ground missiles, a regime monopoly. The direction from which the attack came also fits.
The regime is known to have targeted its own people previously and blamed the rebels. That includes some of the slaughters of civilians by beard-wearing shabihha. Why beards if they hated Islamists? And why is several cases with regular military nearby? Would the latter have stood buy is those slaughtering civilians were rebels?
WHAT THE ANALYSIS CLEARLY PROVES
A regime jet approaching first from the direction of a military airport fired the first missile and on its return fired a second missile. Sound and other analysis confirms this. The second attack makes it obvious that the intent was deliberate. This was no accident.
FURTHER SUPPORT FOR THE CHARGE
It also fits descriptions from hundreds of witnesses. Finally no trace of an exploded vehicle could be found.
