Turkey’s deadly air strikes sparked disturbances in the country’s restive mainly Kurdish southeast.
As youths and police clashed, Kurdish activists denounced what they labelled a war crime, calling for Turkey to be judged under international law.
A PKK commander urged Kurds to rise up after what he called an organised and planned massacre.
The deaths threaten to ignite more violence from the PKK itself, regarded as a terrorist organisation by Turkey, the EU and the US. The group has been fighting for an ethnic Kurdish homeland in a conflict that has claimed some 40,000 lives.
