Feds warn about threats to Israeli and Jewish institutions and supporters in U.S.

Washington — Federal law enforcement agencies have issued a new intelligence bulletin, obtained by CBS News, warning that recent attacks in Boulder, Colorado, at the Capital Jewish Museum in Washington, D.C., and at the Pennsylvania governor's residence "could motivate others to conduct violence against Israeli and Jewish institutions, or their supporters."

The memo was issued by the Department of Homeland Security, the FBI and the National Counterterrorism Center to law enforcement nationwide Wednesday, voicing concern that "some individuals online are sharing the manifesto of the alleged Capital Jewish Museum attacker, praising their actions, and calling for additional violence."

"We advise security partners to remain vigilant for threats of targeted violence against Jewish and Israeli communities, and their supporters," the memo says.
