ALBANY – A series of anonymous bomb threats was made against more than a dozen Jewish community centers across New York on Sunday, according to state law enforcement officials.

The threats, first reported at 11 a.m. Sunday morning, were emailed to members belonging to 18 JCC's across the state, including the Sidney Albert Albany Jewish Community Center in Albany.

A spokesman for Gov. Andrew Cuomo on Sunday afternoon said the threats are believed to be part of a wider series made against JCC's nationally.

Each of the threats was emailed to individuals separately, said Michael Kopy, the state's director of emergency management. It's unclear if certain individuals were being targeted.

"It's probably best not to discuss why these people were selected and let the investigators work on that right now," Kopy said.

More than 100 people were evacuated from the JCC in Albany as a precaution Sunday morning. State and Albany City Police swept the building.

No bomb was found but the facility remained closed.

Cuomo arrived on scene about an hour after the threat was first reported.

"These types of situations are so ugly and so unfortunate. What's worse is we're seeing more and more of them," he said.

At least 42 antisemitic incidents have been reported across New York in recent months, Cuomo said.

Antisemitism across the country, Cuomo said, is "only getting worse."

"There is a contagion of hate all across this country," he said.

This is not the first time bomb threats have been made against JCC's in New York.

A series of nationwide bomb threats called into JCC's in 2017 led to the evacuation of facilities in Tarrytown and New Rochelle.

An investigation into Sunday's threats is ongoing.
