Jewish groups and leaders across the United States expressed horror and solidarity with the American Muslim community following a deadly shooting at a mosque in San Diego, calling the attack a devastating reminder that hate-motivated violence threatens every house of worship — and every community of faith.

Three people were killed at the Islamic Center of San Diego, which also houses a school, in what local law enforcement described as a hate-motivated attack. Among the dead was a security guard at the mosque whom police called “heroic,” crediting him with preventing an even greater tragedy. The identities of the other victims had not yet been publicly released at the time of reporting.

Two suspects — aged 17 and 18 — were found dead of self-inflicted gunshot wounds near the scene. Law enforcement said the precise motive was still under investigation, but confirmed that “hate rhetoric was involved,” apparently referencing a note left by the younger suspect, which was discovered by his mother, who then contacted police. The suspects’ names were not immediately released.

Jewish California — the umbrella political advocacy organization representing Jewish communities throughout the state — said it was “horrified and heartbroken” by the deadly attack. The organization joined a growing chorus of Jewish institutions nationwide to issue statements of grief and solidarity, framing the violence not merely as an attack on one community, but as an assault on the shared fabric of American religious life.

JFNA: Protect All Houses of Worship

The timing of the attack carried a painful irony. The Jewish Federations of North America (JFNA) noted that the shooting came just as hundreds of Jewish leaders were heading to Capitol Hill to lobby Congress for a major increase in the federal Nonprofit Security Grant Program — from its current $300 million to $1 billion — a fund that can be used by synagogues, mosques, churches, and other institutions to enhance security.

The JFNA’s full statement called on Congress to act swiftly, arguing that the San Diego attack demonstrated precisely why increased federal investment in security for religious nonprofits is urgently needed. The grant program, advocates say, has already enabled hundreds of congregations to install cameras, hire trained guards, and harden entry points — investments that can mean the difference between mass casualties and a thwarted attack.

A Pattern of Politically Motivated Violence

The San Diego mosque shooting did not occur in a vacuum. It arrives amid what experts and community leaders have described as a dangerous spiral of politically motivated violence targeting religious and civic institutions across America.

The pattern has alarmed interfaith coalitions, civil rights organizations, and elected officials alike. Community leaders say the incidents reflect a broader climate of polarization in which religious identity — Jewish, Muslim, or otherwise — has become a target for extremists on multiple ends of the political spectrum.

A New Fellowship for Jewish–Muslim Voices

Even as grief spread through the interfaith community, a note of hope emerged. Social media creator and entrepreneur Nuseir Yassin — widely known as Nas Daily — announced a partnership with the David Merage Foundation to launch a content creation fellowship for 50 Jewish and Muslim creators. The initiative honors the legacy of his late friend Zaki Djemal, whose commitment to cross-community understanding leaves a living legacy in the fellowship program.

The fellowship is intended to produce storytelling that bridges divides, challenges stereotypes, and amplifies voices working toward coexistence — a mission that felt all the more urgent in the wake of the San Diego attack.

UJA-Federation and JCRC Boycott Mayor’s Shavuot Reception

In New York City, community tensions took a different form. The UJA-Federation of New York and the Jewish Community Relations Council–New York (JCRC-NY) refused to attend Mayor Zohran Mamdani’s Shavuot reception, publicly accusing the mayor of inflaming local tensions and of rejecting Israel’s legitimacy as a core pillar of Jewish heritage and identity.

The boycott marked a significant rupture between the city’s largest Jewish institutional bodies and its newly elected mayor. The JCRC and UJA-Federation have historically sought to maintain working relationships with City Hall regardless of political differences, making the decision to publicly decline the holiday invitation all the more notable.

The dual stories — of Jewish solidarity with Muslims in the aftermath of the San Diego massacre, and of friction between Jewish institutions and New York’s mayor — illustrate the complex, sometimes contradictory pressures facing American Jewish communities navigating a fractured political moment.

An Injury to One Is an Injury to All

For organizations like Faith & Freedom News, which covers the global landscape of religious persecution and interfaith relations, the San Diego shooting underscores a principle that has animated advocacy work for generations: when any house of worship is targeted, the threat is not merely to one community but to the idea of religious freedom itself.

The heroism of the security guard who gave his life to protect others at the Islamic Center of San Diego stands as a testament to that principle. So, too, does the speed and unanimity with which Jewish leaders responded — not with silence, not with equivocation, but with grief, solidarity, and an urgent call for action.
