The number of anti-Semitic incidents in the Czech Republic doubled last year, the Jewish community said Wednesday. In its annual report, the Federation of the Jewish Communities said there were 694 anti-Semitic attacks in 2019 compared with 347 in the previous year. A majority of the attacks — 95% — were registered on the internet, often on disinformation websites, far-right media and produced by activists involved in an international campaign to boycott Israel.
