NEW YORK (Reuters) – Muslim Americans have helped raise more than $78,000 to repair vandalized headstones at a Jewish cemetery in St. Louis, Missouri, according to an online fundraising page, amid attacks and threats against Jewish institutions.

About 170 headstones were toppled or damaged at the century-old Chesed Shel Emeth Society cemetery over the weekend, according to cemetery staff.

Some Jewish groups described the vandalism and threats as the latest evidence that anti-Semitic groups have been emboldened by the election of Donald Trump as U.S. president. His campaign last year drew the support of white nationalists and right-wing groups, despite his disavowals of them.

“Muslim Americans stand in solidarity with the Jewish-American community to condemn this horrific act of desecration,” the fundraisers said on their website. More than 2,700 people had donated $78,546 as of Wednesday afternoon.

Jewish community centers across the United States have reported a surge in bomb threats, all of which have so far proved to be hoaxes. On Wednesday afternoon, the Anti-Defamation League, one of the country’s most prominent Jewish advocacy groups, said its national headquarters in New York City received an anonymous bomb threat but was later given the all clear.

Trump condemned the threats as anti-Semitism for the first time on Tuesday after repeatedly declining to do so when asked by journalists last week. Some Jewish organizations have criticized his approach, saying they fear that the groups that supported Trump had become more active.

The fundraising effort was launched by Linda Sarsour, a liberal political activist, and Tarek El-Messidi, the founding director of Celebrate Mercy, a non-profit organization that teaches the public about Mohammad, the founder of Islam.

On Tuesday night, Sarsour posted on Twitter that she was raising the funds “in solidarity with our Jewish sisters and brothers.”

Sarsour was a supporter of U.S. Senator Bernie Sanders in his bid to become the Democratic Party’s presidential candidate, and went on to become one of the organizers of the Women’s March on Washington, which drew record crowds to the capital on Jan. 21, the day after Trump’s inauguration.

Cemetery staff, who did not respond to a request for comment, were still calculating the cost of repairing the damaged tombstones as of Tuesday. The organizers of the fundraising campaign said they would donate any excess funds to repair “any other vandalized Jewish centers.”
