A new round of bomb threats hit Jewish centers after another cemetery was vandalized

UPDATE 12:13 p.m.:

NBC News reported another "wave" of bomb threats were reported at Jewish community centers in North Carolina, Alabama, Florida, Pennsylvania, New Jersey, Delaware and Indiana.

Dozens of bomb threats have been reported at JCCs since the start of 2017, many concentrated on specific days.

ORIGINAL STORY: Dozens of headstones were toppled and vandalized at a Jewish cemetery in Philadelphia over the weekend. Aaron Mallin was visiting Mount Carmel Cemetery on Sunday and told police three of his relatives' tombstones were damaged.

This comes less than a week after a Jewish cemetery near St. Louis was similarly vandalized and a Tampa mosque was set on fire.  In January, a spike in bomb threats at Jewish community centers was reported nationwide.

Philadelphia Mayor Jim Kenney said those responsible will be "prosecuted to the fullest extent of the law," adding, "Hate is not permissible in Philadelphia."

WPVI in Philadelphia reports more than 500 headstones were damaged. The Associated Press reports the number is closer to 100. 

Israel Foreign Ministry spokesman Emmanuel Nahshon condemned the attacks.

So did Gov. Tom Wolf.

It's not yet clear how much repairs will cost. A GoFundMe page to repair the tombstones with a goal of $10,000 has reached more than $11,000 as of Monday morning.

The Anti-Defamation League is offering a $10,000 reward for anyone with information that leads to the arrest of those responsible. 

Local Muslims quickly stepped in to help with the repair effort.
