ADL offers $10,000 reward for information leading to the conviction of those responsible for vandalism of Jewish cemetery in Philadelphia.

The Anti-Defamation League offered a $10,000 reward for information leading to the conviction of those responsible for the vandalism of a Jewish cemetery in Philadelphia.

More than 100 gravestones were toppled and damaged at the Mount Carmel Cemetery in the city's Wissinoming section. The vandalism was discovered Sunday.

The reward money leading to the arrest and conviction of the vandals is being provided by the Mizel Family Foundation, according to the ADL.

About a week ago, over 150 headstones were discovered overturned and damaged at the Chesed Shel Emeth Jewish cemetery in St. Louis in vandalism that made national headlines. Vice President Mike Pence was among those who contributed to the cleanup effort.

It is not known who committed the vandalism or if the motive was anti-Semitism.

A Gofundme campaign for the Philadelphia cemetery was launched by a private citizen, Raphael Caroline, 31, in the hours after the vandalism was discovered. It reached its $10,000 goal and beyond in seven hours.

The Jewish Federation of Greater Philadelphia also is collecting donations for repairs to the cemetery.

Pennsylvania Sen. Bob Casey in a tweet called the attack on the cemetery "a despicable act of vandalism -- these acts of hate cannot be tolerated."

The state's governor, Tom Wolf, in a tweet called the vandalism "a cowardly, disturbing act. We must find those responsible and hold accountable."

Philadelphia Mayor Jim Kenney said city officials are working to discover who committed the attack.

"My heart breaks for the families who found their loved ones' headstones toppled," he said in a statement. "We are doing all we can to find the perpetrators who desecrated this final resting place, and they will be prosecuted to the fullest extent of the law. Hate is not permissible in Philadelphia. I encourage Philadelphians to stand with our Jewish brothers and sisters and to show them that we are the City of Brotherly Love and Sisterly Affection."

Area Muslims from the Ahmadiyya Muslim Community USA's Philadelphia mosque joined local Jews to help clean up the cemetery.

"They wanted to divide us. We united even more," tweeted Kashif Chaudhry, a physician and Muslim activist.

"This is America," read more than one response.

"This Jewish girl from Philly thanks Muslim community of Philly 4 standing w/us," read another.

A candlelight vigil to support the Jewish community was held on Sunday night.
