The FBI is investigating a flurry of bomb threats reported at Jewish centers in the U.S. and Britain on Monday.
The bomb threats continued to trickle in as the FBI began investigating, the Washington Post reports. 
The threats occurred in places such as the Alper Jewish community campus in the Miami-Dade area and a center in Tenafly, N.J.
At least a dozen threats were reported in the U.S. on Monday.
“It’s disturbing,” said Elise Jarvis, who directs the Anti-Defamation League’s security programs.
It’s unclear what prompted the unusual number of bomb threats.
