Agents from the U.S. Department of Homeland Security are in Chicago to beef up security at Jewish institutions.

They arrived Sunday and are working through the Chicago Jewish federation, according to Paul Goldenberg, national director of the Secure Community Network (SCN), a security agency that is the product of the Jewish Federations of North America and the Conference of Presidents of Major American Jewish Organizations.

On Wednesday, senior Homeland Security leadership will begin a series of conference calls with senior Jewish leaders across the country focusing on increased security concerns in the wake of last Friday’s bomb threat in which two packages of explosives mailed from Yemen and allegedly targeting Jewish institutions in Chicago were intercepted. One was intercepted at a FedEx way station in the United Arab Emirates, and one in London.

Hidden inside printer cartridges, the explosives were powerful enough to bring down a plane. Officials are still trying to determine the intended targets – the planes carrying the bombs or the institutions to which they were mailed.

SCN is “closely monitoring the situation,” said Goldenberg, who is in Chicago working with Homeland Security.
