The leader of Germany's Green party has urged Turkish citizens in Germany and Turkey to vote "No" in the upcoming referendum in Turkey while German officials impose bans on "Yes" meetings and rallies of Turkish ministers on the grounds of meddling with the country's internal affairs.

Cem Özdemir, the co-chair of Alliance '90/The Greens shared a video on his Facebook page, which starts with the word "Merhaba", the Turkish word for "Hello", and continues: "Please, vote "No" in the upcoming election."

The voting in Turkey would also affect whether the Turkish community would be able "to peacefully live in Germany", Özdemir claims in the video, implying that the 1.4 million Turkish citizens living in the country could face difficulties if they voted "Yes" in the referendum.

In an earlier interview with the German Welt am Sonntag newspaper, Özdemir, who is of Turkish-Circassian origin, said that he cannot understand how Turks in Germany could vote "Yes."

The majority of commenters on Özdemir's Facebook page were against the German politician's open call.

The most liked comment posted under his video said "If you are so much interested in Turkish politics, just go to Turkey." Other comments, which were liked by more than 1,200 people, urged the politician to leave his "double standard attitude" aside and instead focus on Germany's own problems.

Turkey-EU relations have been severely strained following a series of bans in Germany, the Netherlands and Austria on Turkish officials' visits for the upcoming referendum campaign in Turkey.

President Recep Tayyip Erdoğan said on Saturday that Turkey may hold a referendum on whether to continue the European Union accession talks after the April 16 referendum.
