Turkish President Erdogan has praised the arrest of a German journalist and accused Germany’s Angela Merkel of using “Nazi measures,” in a fresh attack on Berlin. A Turkish paper also slammed DW for “terror propaganda,” reports.

Ankara launched a new wave of anti-German rhetoric on Sunday, with President Recep Tayyip Erdogan calling out the German chancellor in a televised speech.

“When we call them Nazis, they (Europe) get uncomfortable. They rally together in solidarity. Especially Merkel,” Erdogan said.

“But you are right now employing Nazi measures,” he said, addressing Merkel directly and using the unofficial, personal way of saying “you” in Turkish.

Erdogan has previously accused both the Netherlands and Germany of acting like Nazis after the two countries prevented Turkish ministers from holding campaign rallies on their territory.

In his Sunday speech, Erdogan accused Merkel personally of using Nazi methods against his “Turkish brother citizens in Germany and brother ministers.” The row with Europe “showed that a new page had been opened in the ongoing fight against our country,” he added.

Berlin was decidedly not amused, saying that the Turkish president had “gone too far.” Foreign Minister Sigmar Gabriel told the Passauer Neue Presse that he warned Ankara against continuing this “shocking” rhetoric.

“We are tolerant but we’re not stupid,” Gabriel said. “That’s why I have let my Turkish counterpart know very clearly that a boundary has been crossed here.”

Erdogan also described German reporter Deniz Yucel, who had been arrested  in Turkey, as a “terror agent.” Yucel was initially detained after reporting on emails allegedly coming from the private account of Berat Albayrak, Turkey’s energy minister and Erdogan’s son-in-law.

“Thank God he has been arrested,” the Turkish president said.

Berlin has urged Yucel’s release and rejected earlier claims that he was working as a German spy
