ToursClearly you did not watch the news report I posted.
Perhaps the reason they have not declared so publicly is because of the complicated relationship ISIS has with the Turkish government. I will admit that it does seem odd that they would attack the main purchaser of their illicit oil production.
And if not ISIS (who have already shown that they can and will carry out attacks in Turkey), then who? I'm not sure what you were insinuating by the nationalities (since ISIS has muslims from all over), the one from Russia was most likely from Dagestan, which I hardly consider Russia, but falls within the Russian border. If my memory serves me, Dagestan is also where the Boston Marathon bombers were from.
Blocked on my work network, so no, I have not watched it.
The relationship between Turkey and ISIS was complicated, but under immense pressure from the EU, UN, and US, it began to strengthen its borders as of last summer. That is not to say the borders are patrolled perfectly, nor that there is not shady activity going on between the two groups, but the uptick in attacks on Turkey would indicate that ISIS is no longer happy with the arrangement. Not to mention, ISIS is also facing an oil crunch as the low crude prices combined with allied air attacks on their facilities has meant a declining source of revenue for them.
I believe it is ISIS, but we need to be careful about jumping to conclusions. The PKK is another group in Turkey/Syria that has shown they are not afraid of attacking Turkey as well.
The "Russian" was from near the Chechen border so your assumption was correct. I just found it interesting that they attackers are apparently from these countries, as the majority of the extremists that garner headlines are Afghani, Pakistani, Iraqi, or Syrian. It will be interesting to see what Russia does as they are currently at odds with ISIS as well.
