UPDATE: An all clear has been called at both John Wayne Airport and Skyharbor Airport after authorities declared the threats affecting two Southwest Airlines flights to be bogus.
(SANTA ANA, Calif.) -- Authorities have confirmed to ABC News that two Southwest Airlines flights, one in Orange County, Calif. and another in Phoenix, Ariz., were grounded Tuesday night in isolated areas at John Wayne Airport and Skyharbor Airport, respectively.
The flights were the subjects of threats, with at least one plane said to have possible explosive or hazardous materials. Initial reports indicate that a third Southwest flight may also be involved in the series of threats. Joint federal and local terror task forces have met two flights and are investigating, authorities say.
Southwest flight 811, bound for Phoenix from John Wayne Airport, was moved to an isolated end of the airfield, after a non-specific threat was called into Phoenix authorities, according to a statement from a spokeswoman at the airport in Orange County. Passengers were allowed to deplane and return to the terminal while authorities investigate.
