The German government criticized Turkey on Wednesday after the Turkish interior minister threatened to arrest "terrorists" and "traitors" from Germany arriving at Turkish airports.
The statement from Interior Minister Suleyman Soylu was "not helpful in the current situation," Foreign Office spokesperson Maria Adebahr said in Berlin.
According to Turkish media, Soylu told an election campaign rally on Sunday that people in Europe and Germany who attend "terrorist organization" rallies would be arrested in Turkey.
"In Germany, in Europe, there are those who attend terrorist organization events then go on vacation in Antalya, Bodrum and Mugla," Soylu said, referring to Turkish resort towns. "Now we've taken action against them.
"All right then, let them come and go to prison directly from the airport. Being in prison isn't so easy. From now on it won't be easy to commit treason abroad then come to Turkey for fun and good times," he told supporters.
