German chancellor Angela Merkel has warned Turkey’s President that comparing German officials to Nazis must stop.
“You are right now employing Nazi measures,” Mr Erdogan said on Sunday.
“When we call them Nazis they (Europe) get uncomfortable. They rally together in solidarity. Especially Merkel,” he said in a televised speech.
Mrs Merkel said if President Recep Tayyip Erdogan continues, more campaign events by Turkish politicians may be banned.
German authorities have cancelled rallies designed to woo ethnic Turkish voters ahead of a key referendum on expanding Mr Erdogan’s powers.
She said that Germany reserved the right to “take all necessary measures”, including reviewing future events that had already been granted permission.
Mrs Merkel said that such comments were breaking every taboo, without consideration for the suffering of those who were persecuted and murdered by the Nazis.
As the war of words intensified on Monday, Turkey’s deputy Prime Minister, Numan Kurtulmus, said that Germany was meddling in Ankara’s internal affairs.
