FBI says San Diego mosque shooters were radicalized online

Authorities said two teenagers who killed three people at a mosque in San Diego were radicalized online, where they first met and shared white supremacist views.

The attack has shaken the local Muslim community and renewed concern over violent extremism and online hate networks, which can inspire attacks far beyond one city.

Authorities

Investigators say the two suspects were drawn together online before carrying out the attack, and that their writings showed shared extremist beliefs. They are treating the case as part of a broader pattern of digital radicalization and hate-driven violence.

Local Muslim Community

Community members described shock and grief after an attack they say many believed was unthinkable at a place of worship. Some also pointed to rising anti-Muslim and racist rhetoric as part of the wider climate around the killings.

  • Online extremist communities have helped connect isolated attackers across borders.
  • White supremacist movements have long used propaganda to recruit young followers.
  • Mosques often serve as both prayer spaces and neighborhood support centers.
