(CBS/AP) SAN ANTONIO - Airport operations have resumed and that the situation has been cleared following the evacuation of San Antonio International Airport, sources tell CBS News, after officials say they received a bomb threat alleging three packages had been left inside a parking garage.
Airport spokesman Rich Johnson said that passengers inside the terminal were herded onto the tarmac and that arriving planes are staying parked away from the gates. San Antonio Fire Department spokeswoman Deborah Foster says she doesn't yet know whether emergency responders actually found any packages.
Johnson says the evacuation order was called at 2:35 p.m. Southwest Airlines spokeswoman Ashley Dillon said the carrier has six arriving flights on the tarmac that are waiting for clearance to roll to the gate.
San Antonio Police Chief William McManus said the threat was called in to the airport, saying that three vehicles had explosives, CBS affiliate KENS San Antonio. Two questionable vehicles were cleared and that bomb-sniffing dogs were checking into a third, according to McManus.
Johnson didn't immediately know many passengers were inside the terminal at the time.
KENS, citing sources, said officials were looking into luggage in a parking garage area.
