Turkish Prime Minister Binali Yildirim says Germany is taking sides in Turkey's upcoming referendum and that it's a "grave mistake."

Asked about German Chancellor Angela Merkel's criticism of comments made by Turkey's president accusing Germany of "Nazi practices." Yildirim says Germany "may be disturbed" that a yes vote is likely on the referendum. He says if that's true, it amounts to "meddling" in another country's affairs and is "very wrong"

Yildirim said Thursday through a translator that Germany's claim that it doesn't meddle in others' affairs is unconvincing. He added, "Tell that to someone else."

Yildirim says Germany's restrictions on Turkish politicians campaigning in Germany will have the opposite of Germany's intended effect. He says the Turkish people are taking note.
