An Israeli-American teenager is suspected of calling in bomb threats against Jewish community centres across the United States.

Israeli police on Thursday arrested the 19-year-old who holds citizenship in both Israel and the US. The FBI worked in tandem with Israeli national police over the span of several months.

“Investigating hate crimes is a top priority for the FBI, and we will continue to work to make sure all races and religions feel safe in their communities and in their places of worship,” FBI spokeswoman Samantha Shero told The New York Times.

The Anti-Defamation League has recorded more than 120 bomb threats against Jewish community centres across the US since 9 January, elevating fears of anti-Semitism in the country.



Israeli police spokesman Micky Rosenfeld said the suspect, who comes from the south of Israel, used “advanced camouflage technologies” to cover his tracks and mask the origin of his calls and other communications to synagogues, community buildings and public venues.

He added the suspect sent dozens of threats to public venues, synagogues, and centres in the US, New Zealand and Australia. The suspect also sent threats to Delta Airlines in 2015, forcing one flight to make an emergency landing.

The arrest is separate from the case of a St Louis man who was arrested earlier this month for threatening eight Jewish centres. Authorities said the man was attempting to harass his former girlfriend.
