A 19 percent decrease in the number of antisemitic assaults recorded worldwide in 2020 from the previous year was attributed to lockdowns connected to the Covid-19 pandemic, according to an annual report published Wednesday. The lockdowns limited personal interactions generally, the authors of the Antisemitism Worldwide report said. There were 371 cases of physical assaults last year. Vandalism, however, increased by 25 percent. Antisemitic activity against cemeteries and Holocaust monuments rose to 96 incidents “because these sites are open and unprotected,” the annual report by the Kantor Center at Tel Aviv University said. The prevalence of antisemitic rhetoric increased online, as well, with much of it coming from conspiracy theorists writing or speaking about the pandemic.
