In his most bitter reaction yet to the vote by the German parliament Thursday to recognise the killings from 1915 as genocide, Erdogan threatened to leave Europe "to its own worries" if such disputes were not resolved.
"The issue here is not the Armenians.... The Armenian issue is used all over the world as a convenient blackmail against Turkey and has even started to be used as a stick," he said in a televised speech.
He said that during World War I, what remained of the Ottoman Empire was "under siege from all sides" and "of course a number of measures were taken to restore order in Anatolia".
Referring to Germany's guilt over the Holocaust, Erdogan scoffed that it was the "last country" to make such accusations.

He added Germany would also be better advised to re-examine the the slaughter of indigenous Namibians under the German Empire over a century ago, which Berlin has yet to officially term a genocide.
"Either we find solutions to our problems in a fair way. Or Turkey will stop being a barrier in front of the problems of Europe. We will leave you to your own worries," Erdogan added to cheers, without specifying further.
