Britain’s Scotland Yard and the US Federal Bureau of Investigation are investigating more than a hundred bomb threats made to Jewish groups in the United States and the UK since January 7, US and UK law enforcement and Jewish community officials said.
Investigators said there is evidence that some of the US and British bomb threats are linked. According to people in both countries who have listened to recordings of the threats, most of the them have been made over the telephone by men and women with American accents whose voices are distorted by electronic scramblers.
Waves of threats against US Jewish groups - including community centres, schools, and offices of national organisations such as the Anti-Defamation League (ADL) civil rights group - have been followed within hours by similar but smaller waves against Jewish organisations, mainly schools, in Britain, Jewish community representatives in both countries said.
FBI officials in Washington confirmed that the agency is investigating the threats against US Jewish organisations. Sources in Britain's Jewish community said London's Metropolitan Police, otherwise known as Scotland Yard, is conducting its own investigation and collaborating with the FBI.
Some of the most recent threats were called in Tuesday to ADL offices in Atlanta, Boston, New York, and Washington. White House spokesman Sean Spicer said President Donald Trump's administration would "continue to condemn them and look at ways to stop them."
The threats, 140 of them in the United States alone, according to Jewish community leaders, usually have involved callers claiming that improvised explosive devices have been placed outside the buildings that have been threatened.
