Teenagers Kill Three at San Diego Mosque and Leave Neo‑Nazi Manifesto

Authorities are treating the attack as a hate crime, prompting renewed efforts to restore state security grants for houses of worship.

Overview

  • The shooting took place Monday when two teenagers stormed the Islamic Center of San Diego, killing security guard Amin Abdullah and two other men before the attackers died by apparent suicide.
  • Surveillance and witness accounts show Abdullah exchanged gunfire and radioed a lockdown that protected about 140 children, and his family and community leaders have called him a hero.
  • Investigators recovered a 74‑page manifesto, Nazi symbols and white‑supremacist material that namechecked prior far‑right attacks and groups, and law enforcement is treating motive as part of an active hate‑crime probe.
  • Researchers say the document and online activity link the attackers to accelerationist neo‑Nazi currents — an ideology that urges violent acts to trigger social collapse — a pattern seen in past mass‑attacks.
  • Local officials and civil‑society groups have mobilized security and mourning efforts, and San Diego leaders secured Gov. Gavin Newsom’s agreement to seek $40 million to restore California’s nonprofit security grant program now before the legislature.
