As a retaliatory measure, Germany is considering withdrawing its Bundeswehr servicemen from the military base and transferring them to Jordan.
According to political observer Vladimir Ardaev, the current situation could further contribute to deteriorating bilateral relations between the countries.
"This could mean a new round of tensions between Berlin and Ankara — the most serious one in recent times," Ardaev wrote for RIA Novosti.
According to Der Spiegel, the decision by the Turkish authorities to ban German diplomats from visiting its military base could be viewed as a response to the recent initiative of the German government, according to which it decided to grant asylum to a number of Turkish military.
Since the failed military coup in the summer of 2016, the Turkish authorities have arrested thousands of people suspected of plotting it.
"Those who found shelter on German soil are seen as supporters of the Islamic preacher and dissident Fethullah Gulen, who lives in the US and Erdogan calls the main organizer of the coup," Ardaev wrote.
Although German diplomats do not give up hope for a settlement of the new conflict with Turkey, many experts and politicians believe that the conflict will hardly be resolved in the short run.
