For Jewish activists, Yom Kippur became a day to mourn Palestinians

Hundreds of Jewish New Yorkers gathered at Brooklyn's Grand Army Plaza on Yom Kippur, Sept. 21, 2026, for a public mourning ritual that memorialized Palestinians killed in the Israel-Hamas war and criticized Israel's conduct. The event came days before Israeli Prime Minister Benjamin Netanyahu's U.S. trip for the U.N. General Assembly and featured remarks from Brad Lander, a Jewish Democratic congressional nominee, who called attention to what he described as a "genocide" in Gaza. Organizers included Jews For Racial & Economic Justice and Rabbis for Ceasefire, a collective of about 80 Jewish clergy; the service was co-sponsored by Jewish Voice for Peace, IfNotNow and the American Council for Judaism. Palestinian activist Mahmoud Khalil, detained by U.S. Immigration and Customs Enforcement in 2025 after his green card was revoked, addressed the crowd and said repentance is difficult while U.S. policy funds violence; Khalil is suing the Trump administration and Columbia. The gathering highlighted divisions in New York over Netanyahu's visit, which followed Mayor Zohran Mamdani's public criticism and later walk-back of an arrest pledge; Netanyahu called the mayor's earlier comments hate fomenting and said they fueled antisemitism. In recent days opponents and supporters of Israel staged competing actions in the city, including Modern Orthodox teens praying with tefillin outside Gracie Mansion to show support for the Israeli government.

As Yom Kippur came to a close this evening, I was privileged to join my friend, Ruth Messinger, at a break fast in her home. It was an honor to celebrate this moment of renewal with many of our Jewish neighbors. May it be a year of justice, joy and peace.

I talked to Jews across America, from Alaska to Brooklyn, about how they mark Yom Kippur, Judaism's holiest day. Their stories were deeply personal, profound, and sometimes quite funny. I hope you read every single one and that it enhances your experience or understanding of the day. Gift link:
