Jewish organizations faced another wave of threats in the city and across the country. 

Several Jewish community centers and day schools have received bomb threats so far this week.  

And the Anti-Defamation League says offices in Manhattan, Atlanta, Boston, and Washington received telephoned bomb threats on Tuesday.

Officials at the ADL's national headquarters in Murray Hill say they evacuated the building as a precaution.

"It was all clear. It was a non-, a non-threat after NYPD and our security in the building and our ADL security did a thorough sweep," said Evan Bernstein, NY director of the ADL. "This deeply affects the communities when young people, children, are taken out these JCCs and elderly people that are there for programming are being affected, it's very, very difficult for these communities, and it's imperative that law enforcement continue to be diligent." 

Since January, officials have been investigating more than 120 threats against Jewish sites in three dozen states and a rash of vandalism at Jewish cemeteries.
