This incident seemed to be committed by suicidal bombers, aiming at a “Labour, Peace and Democracy” rally organized by the Confederation of Progressive Trade Unions of Turkey and some relevant organizations.
In Ankara, there have been some bombing cases occurred so far. But this case is ranked as the deadliest one in Turkey’s modern history.
This case was deemed as a terror at the beginning. But no one published the criminal declaration. Usually, a group of terrorists make a commitment to their antisocial activity to make a provocation to the authorities and inflict the fear of citizens. There were some possible groups likely to do such a destructive act, considering the complicated situation of Turkey.
I thought that one of the aims of the criminals was to cause a suspicion among citizens.
Recently, it was reported that the suicidal bombers were identified with DNA investigation. According to the authorities, they are likely to have linked to Islamic State. It is not a surprising result.

Turkey is struggling to deal with the tense relationship between Western countries and Islamic ones. It is inevitable that this tragedy will influence on the national emotion against Islamic extremists. On the other hand, Turkish police were also blamed as they were responsible for the prevention of terror attacks.

Anyway, harming others with forcible ways is not permitted at all. I strongly hope such cases will never occur.
