It doesn't make much sense for this to be a missile strike. Also the video quality is so bad, it actually looks like it's intentionally made bad after the fact, to make the hide the potential edit of that line in the sky.. Not saying it's definitely fake, but I'm definitely skeptical.

I also don't believe this is just a one man suicide. If it is, I would expect we will get the full story of what explosive were used, how he got hold of them, how he prepped the explosives, etcetera. Whether or not they are sparse on the details of those.. will be an indication for me whether this was an actual suicide (which I doubt) or a targeted operation.
