The national offices of the Anti-Defamation League in New York have received an anonymous bomb threat.
Jonathan Greenblatt, CEO of the organisation, tweeted a message confirming the incident. He wrote: "This morning @ADL_national received a bomb threat. We're just one of many #Jewish groups that has been targeted."
In a longer statement, he added “While there is no information at this time to indicate that this is more than a threat, we are taking it very seriously. We are working with law enforcement officials to determine if it is connected to similar threats against Jewish institutions across the country."
“This is not the first time that ADL has been targeted, and it will not deter us in our efforts to combat antisemitism and hate against people of all races and religions.”
The threat in New York followed a number of others across the USA. These included a Jewish community centre in San Diego, which was evacuated after receiving an emailed bomb threat.
The Lawrence Family Jewish Community Center in California received its second threat in three weeks on Tuesday morning.
The San Diego Police Department attended the building after it was alerted to the threat, but did not find any explosives.
A day earlier, 11 Jewish community centres across the country received telephoned bomb threats.
Meanwhile, police in Toronto, Canada, are investigating after antisemitic notes were found on the doors of Jewish residents in the city.
Post-it notes marked with a swastika and the words “No Jews” were found on the front doors of residences.
Some residents also reported that their mezuzahs had been vandalised.
