A New Jersey Synagoge was evacuated March 22 after receiving a phoned-in bomb threat. This was the last bomb threat before the FBI announced the arrest of a man in Israel suspected of making dozens of threats this year.

On March 14 and 15, at least four JCCs received bomb threats. For most of the centers, this was not the first bomb threat this year.

In four out of the five days since the last wave of threats, there was at least one bomb threat per day aimed at U.S. Jewish institutions.

On March 7 and the early morning of March 8, at least 18 locations of Jewish organizations received bomb threats.

In the fifth and largest wave yet, bomb threats were called into at least 35 organizations, including schools, JCCs and an office of the Anti-Defamation League.

Between waves four and five, bomb threats forced several Jewish organizations to evacuate, including the New Orleans JCC, the Manhattan offices of the Anti-Defamation League and a Jewish day school in Durham, N.C.

In the fourth wave, bomb threats were phoned in to at least 12 Jewish Community Centers.

Between waves three and four, the Hillel Day School near Detroit evacuated after receiving a vague emailed threat.

In the third round of nationwide bomb threats, 15 JCCs, including a day camp in Chicago, were evacuated.

Just a week after the first wave, a second round of bomb threats were called into at least 27 Jewish organizations, including a few that had already received threats in the first wave.

Between the first and second wave of calls, the Israeli consulate in Miami evacuated due to a bomb threat, and the JCC of Staten Island was evacuated after swastika graffiti with the word “bomb” was found on a bathroom wall.

In the first nationwide rash of bomb threats, robocalls made to at least 15 Jewish organizations forced evacuations and panic.

In a precursor to later events, three Florida Jewish organizations and the Atlanta Jewish Academy were evacuated after bomb threats between Jan. 4 and 5.
