Jewish Community Center
There's been an increase in anti-Semitic incidents in recent weeks.
Eleven Jewish community centers received threats.
"I’ve never seen a string of attacks like this that are targeting the same kind of institution in the same kind of way. This is new."
Calls like this have come in waves, and there's no sign they'll be stopping.
WHAT'S HAPPENING
A total of 14 centers across 10 states, along with one in Canada, received the threats.
They received at least 20 threats on Wednesday.
The calls to Jewish schools and centers in nine states all occurred within the span of one day.
