Chancellor Angela Merkel is calling on Germany’s Turkish community to show loyalty to the country.
Speaking to a regional newspaper group, she said: “We expect from people of Turkish origin, who’ve already lived in Germany for a long time, that they develop a high level of loyalty to our country.”
She also stressed that Germany would listen to any concerns and warned against stoking any political unrest.
Merkel’s words come amid a continued crackdown in Turkey following the failed coup. Last month, thousands of protesters turned out in Cologne to demonstrate against the revolt.
Reports suggest President Recep Tayyip Erdogan could be pressing Turks abroad to show more loyalty to Ankara.
Around three million people with Turkish roots live in Germany.
