Paul Goldenberg, the director of Secure Community Network - an affiliate of the Jewish Federations of North America that advises Jewish groups and institutions on security - said the threats were called in late Tuesday morning. Some of the messages were live, he confirmed.
'[I]n the past we know that the numbers can grow exponentially,' he said, adding that perpetrators have been 'leveraging technologies to make mass calls.'
Goldenberg confirmed that threats had been called into JCCs in Albany, New York; Syracuse, New York; West Orange, New Jersey; Milwaukee, San Diego and Salt Lake City...
On Jan. 18, some 30 Jewish institutions in at least 17 states received bomb threats. On Jan. 9, such threats were called into 16 JCCs across the Northwest and South, forcing the evacuation of hundreds."
