Shalicar, was reading segments of the book to a crowd of approximately 100 people, when a group of activists form the BDS movement began playing loud music and shouting "baby killer" and "representative of an apartheid state" at him.
Audience members shouted the BDS activists down and the event proceeded as planned.
The activists were detained by police. One of them was indicted in the U.S. in 2017 after he interrupted a public with an Israeli member of Knesset.
On Monday, the German parliament passed a motion defining the boycott, divestment and sanctions movement as anti-Semitic.
The motion, backed by Chancellor Angela Merkel's CDU party, Is non-binding but stipulates Germany must resolutely condemn calls to boycott Israel.
Shalicar, an official of the Ministry of Intelligence, in the outgoing Israeli government, said this disturbance proves that there is anti-Semitism in Germany and in the BDS movement.
These people who interrupted my book event, are not interested in dialogue. I would have answered any of their questions. These are radical BDS activists who support terror in the way they de-legitimize Israel. The audience could see what radical left anti-Semitism looks like.
Shalicar's new book, called "The New German anti-Semitism, Do Jews today belong to Germany"
In a separate incident, Students at a University in California, in Los Angeles interrupted a gathering of Israelis and Kurds shouting slogans calling for a free Palestine.
