The latest destruction comes amid a series of bomb threats and vandalism targeting Jewish institutions, including cemeteries, schools and community centers.
Last week, at least a dozen headstones were toppled at a Jewish cemetery at the Waad Hakolel Cemetery in Rochester, New York, following similar incidents in St. Louis and Philadelphia. In late February, at least 170 headstones were damaged at a Jewish cemetery in St. Louis.
