The FBI recently warned California police that Iran could potentially launch drone attacks on the West Coast in retaliation for U.S. strikes, though details on timing, targets, or methods remain unclear.

The alert, issued before ongoing U.S. and Israel attacks on Iran, indicated that the 12-day bombardment may have significantly reduced Iran’s capabilities.

U.S. intelligence has also flagged the risk of Mexican drug cartels using drones with explosives against U.S. forces along the border.

California authorities, including Gov. Gavin Newsom’s office and the LA Sheriff’s Department, have increased patrols and preparedness around cultural sites and places of worship, ABC News has reported.

Experts warn that pre-positioned drones, whether on ships or land, could be used in surprise attacks, highlighting a growing concern over drone warfare threats from both the Pacific and Mexico.
