'You Will All Land in Gas Chambers,' Berlin Man Tells Israeli Restaurateur in Viral Video

German Justice Minister condemns the rant, which follows a flare-up in German anti-Semitic sentiment since Trump's announcement on Jerusalem recognition

Video footage showing a 60-year-old German man hurling anti-Semitic abuse at an Israeli restaurant owner in Berlin had been shared 300,000 times on social media on Thursday, with police saying the perpetrator had been detained.

The girlfriend of Yorai Feinberg, the owner of Restaurant Feinberg's in Berlin's Schoeneberg district, shared a video on Facebook that showed the man approaching them outside the restaurant and embarking on a 6-minute anti-Semitic rant. 

"Why did you stay here after '45," the man says in the video, referring to the end of the Third Reich, during which 6 million Jews were murdered at the hands of the Nazis

"No-one will protect you: You will all land in the gas chambers," he says shortly before a police car is seen arriving at the scene.

German Justice Minister Heiko Maas has condemned the video. "This completely outrageous and inexcusable incident in Berlin shows that we must all oppose anti-Semitic rabble-rousing in a dedicated and courageous manner," Maas said on Twitter.

Police said in a statement released late Wednesday that they had detained the man, and that he had acted aggressively and verbally abused the police while being handcuffed.

The statement added that the man was now under investigation for hate speech and incitement to violence. 

Facebook temporarily deleted the video, but later restored it and apologized. "Our reporting systems are configured to protect people from abuse, hate speech and bullying and we apologize for the fact that occasionally mistakes are made," a spokeswoman said.

The debate about anti-Semitism in Germany has flared up in recent weeks as hundreds of Arabs and Palestinians took to the streets to protest U.S. President Donald Trump's recognition of Jerusalem as the capital of Israel.

Some participants in the protests were seen burning Israeli flags and shouting anti-Semitic slurs.
