This bombing of peace and pro-Kurd activists/demonstrators was no accident and certainly accomplished with at least tacit consent from the Turkish military dictatorship, to whom we give consent for their state-terrorism bombing the Kurds in Syria - likewise Saudi bombing of Houthis in Yemen and Israeli bombing of Gaza - a giant cluster-farce with the US at center stage!
The US supports and arms all these usual suspect terrorist states bombing or occupying or waging lower-level war on dissent, from Turkey, the Saudis, Israel, Egypt, and of course the debacle and sectarian violence (including the creation of Daesh/ISIS depravity) in/from what used to be Iraq - all brought to the world by the good-old USA!
The US has become example for war crimes and oppression of millions that these and other states use as "justification" for their own atrocities, like bombing hospitals! We have adopted and spread the Israeli model of "dealing with" anyone that opposes our endless wars!
We have become the enemy, and good friend to multi-state terrorism - really fine work Mr President! How does that Nobel Peace Prize feel now?
