Watch this thermal imaging video, and at 0.07 seconds you can see an object move down in a diagonal line very fast from the top left corner towards the center of the explosion, suggesting an air-to-surface missile was used. The more you watch it, the clearer it becomes.
However, there are other reports saying that this video is faked, in order to spread confusion and misinformation.
Other reports suggest that a Directed Energy Weapon (DEW) was used.
Screenshot just b4 blast. You be the judge.
Do you see a disturbance in the air? A defined line of light that altered the air just b4 the massive explosion?!
As always, do your own research and come to your own conclusions.
