Three worshippers died Monday during a shooting at the Islamic Center of San Diego in the Clairemont neighborhood [1].

Law enforcement officials are treating the attack as a hate crime, signaling a violent escalation of racial-supremacy ideologies targeting religious minorities in the U.S.

Mayor Todd Gloria said the attack was a "violent act of hate" [2]. According to investigators, the shooting was motivated by hate-filled, racial-supremacy ideology that the suspects expressed online and in commentary [3].

Two teenage gunmen were identified as the suspects in the attack [4]. Both suspects later died by self-inflicted gunshot wounds [1]. An FBI spokesperson said the teenage gunmen were connected online over hate-filled ideology [5].

The victims included three adults [1]. In a separate statement, the mother of one suspect said her son was suicidal and possibly armed [6].

Investigators are continuing to review a weapons manifesto and online activity to determine the full scope of the suspects' coordination [7]. The incident occurred at the Islamic Center of San Diego, where worshippers had gathered [4].

"It was a violent act of hate."

This incident highlights the role of online radicalization in mobilizing minors to commit mass violence. By linking the suspects through racial-supremacy commentary and a shared digital ideology, the case underscores the challenge law enforcement faces in monitoring decentralized, internet-based hate groups that target specific religious institutions.
