FBI warns California police of unverified Iranian drone attack aspiration amid US-Iran war

The FBI issued a memo to California law enforcement warning of unverified information that Iran aspired in early February 2026 to launch a surprise drone attack from a vessel off the US coast against unspecified targets in the state, in retaliation for potential US strikes. This alert surfaced during the ongoing US-Israel war with Iran that began on February 28. Officials including Governor Gavin Newsom downplayed any imminent threat, stating no specific intelligence supports it, while maintaining elevated readiness and monitoring efforts.

  • California hosts the largest Iranian diaspora in the US, up to 500,000 residents.
  • Iran has a history of alleged plots targeting US-based dissidents.
  • US strikes reportedly degraded Iran's drone capabilities significantly.
