Possible perpetrators of Paris attack

Thus, they call on both parties in the talks to avoid any steps in the wake of such incidents that will place the negotiations at risk.

More attacks of the same nature may occur in the following weeks or months; we must be well-prepared for these, says Radikal's Koray Çalışkan. The columnist says Deputy Prime Minister Bülent Arınç's message delivered right after the attack, in which Arınç expressed his sadness over the incident and condemned the violent extrajudicial murder, shows the government's strong motivation in solving the Kurdish issue.

Pondering who might have committed the murder, Çalışkan says the initial statements from the PKK point to the deep state and that there is indeed a possibility of that. But it is quite a weak one, he notes. “There are still many Turkish hitmen living in Europe, but these people have neither the motivation nor reason to carry out such an operation. Another possibility is an execution from within the PKK. This is what most of the people believe. But then it is hard to believe that a serious internal fight within the terrorist organization would intensify at such a fragile time to the extent that a co-founder of the terrorist organization would be killed," Çalışkan says. The only possibilities left out, then, are either that it was a personal issue, like a relationship -- even though that possibility is unlikely, or that it was the work of international actors who are worried that once the Kurdish issue is overcome, there will be no obstacle on Turkey's path to becoming a world power. This is the most likely option for now, the columnist says.

In his article in Milliyet, Hasan Cemal calls both on the government and the commanders in Kandil, the PKK's headquarters in northern Iraq, to not be carried away by provocations like the murders in Paris. “Making peace is always more difficult than making war because conspiracies, provocations and assassinations always follow peace negotiations. We know it best because we have seen a lot of these in the past. If we truly take the government's latest initiative for peace seriously and are determined to reach a permanent result this time, we need to carry on our efforts for peace no matter what happens. The government, Öcalan and PKK commanders in Kandil should be especially careful and act responsibly now, because the public has begun to foster enormous hope once again and disappointing them will cost far more than it has ever cost,” he writes.
