JTA: A U.S. Jewish security network has ramped up daily communication with federal, state and local law enforcement agencies in light of Middle East fighting.Although there has been no specific threat against any U.S. Jewish institution, the Secure Community Network, is speaking �constantly� with these agencies, said Paul Goldenberg, SCN�s national director.�At this point in time there is nothing specific that says Hezbollah is planning an attack on Jewish institutions to the best of our knowledge,� he told JTA. �However, they should as a community remain vigilant. With escalated fighting, there�s always a concern that there are people out there that don�t await orders from any particular place.�
