The original refusal came after the German parliamentary passed a resolution declaring the 1915 massacre of Armenians by Ottoman forces "genocide," which Turkey denies. The latest refusal follows the granting of asylum in Germany to a number of Turkish military staff who fear arrest in Turkey for allegedly supporting the failed military coup there, July 2016.
Germany is also demanding the release of Deniz Yucel, a German-Turkish journalist working for Die Welt newspaper. He was arrested and detained on charges of supporting a terrorist organization and inciting public violence.
He is one of six German citizens detained in the crackdown on followers of exiled Turkish cleric Fethullah Gulen, now living in the US, who Turkish President Recep Tayyip Erdogan blames for being behind the failed coup.
Relations between Germany and Turkey worsened still after the publication, September 2016, of the front cover of the respected German magazine Der Spiegel, which showed Erdogan wearing sunglasses reflecting two minarets as rockets taking off from a mosque and describing him in an article as a "Dictator."
Prior to that, there was diplomatic row between Berlin and Ankara when German satirist Jan Bohmermann broadcast a poem on ZDF television sitting in front of a portrait of Erdogan, reading out a poem that accusing the Turkish president of "repressing minorities, kicking Kurds and slapping Christians while watching child porn," among other things. Erdogan demanded that Bohmermann be prosecuted, but plans to do so were eventually dropped.
