To be frank, it doesn't matter who physically planted the bombs (be it suicide bomber or not), what matters is who instigated it and who has most to gain from it.
The PKK bombing their own people under a "false flag" operation as has been suggested by several government officials? Nah, just doesnt add up - they'd have known that a massive military retaliation (as we seen yesterday) would follow any act like this. Plus, they're not going to target the only political party (HDP) that gives them hope of a peaceful resolution and it's been a few years since they targeted "civilians", a policy I suspect they're unlikely to return to.
IS... well, they're an easy organisation to finger as the "bad guys" given their track record, but we've seen no claims by them that they were responsible. Their PR department is slicker than many Fortune 500 companies and I can't see them passing up an opportunity to take the credit for this horrific act.
So who does that leave us with, and what organisation is likely to be the ultimate beneficiary of the events on Saturday?
If it creates sufficient unrest within Turkey it gives the president a chance to declare a state of emergency, that's one benefit.
If it gives the Turkish government the excuse (in the eyes of the West) to step up bombing raids in the Kurdish held areas of Syria, that's another benefit.
If it loses the HDP votes, from those who traditionally wouldn't have voted HDP, over the possibility it was the PKK thats another benefit.
In my opinion, if the Turkish government were not behind this bombing then it is purely by chance and coincidence that they will profit enormously from it. In fact, it ticks so many of the boxes in their current wishlist that they couldn't have planned it better themselves... or did they?
For fear of sounding like a conspiracy theorist I'll leave it at that.
