In the streets of Paris, the protesters blamed Turkey.
"Where are French? Where is that solidarity? I think that the state of Turkey did this," said one man in the Paris crowd, identifying himself only as Ali.
Turkey frequently accuses, France, Germany and the Netherlands — home to large numbers of Kurds from Turkey — of supporting the PKK, failing to extradite wanted militants and of not backing Turkey's "fight against terrorism."

France has a large Kurdish community concentrated in the Paris region and French police have occasionally arrested Kurds suspected of illegally financing the PKK.
