(JTA) – A Jewish Community Center in Silicon Valley and a Brooklyn Jewish senior center both received bomb threats last week. The Addison-Penzak JCC in Los Gatos, California, was evacuated Thursday, March 9 after receiving a bomb threat at 11:45 a.m. The building also includes a day school and the local offices of the Jewish federation and Jewish Family Services, a social service group. Law enforcement determined that the threat was a hoax. Another bomb threat was received Friday morning, March 10, by the Jasa Senior Citizen Center in Brooklyn, New York, via text message. The threat came one day after the Jewish Children’s Museum in Brooklyn was evacuated due to a threat.

These latest threats come days after a wave of bomb threats on March 8 hit 20 JCCs, day schools and offices of the Anti-Defamation League. In total, more than 100 bomb threats have targeted Jewish institutions since the beginning of the year.
