San Antonio Police Chief Bill McManus said their bomb-sniffing dogs had "hits" for possible explosives on three vehicles in the lower level of the short term parking garage.

Chief McManus said bomb techs are now suiting up to check out the vehicles. McManus also said bomb techs are checking Terminal A. Terminal B has been "swept" but they are not sure if there are any explosives. Terminal B is the only area that is back open right now.

San Antonio International Airport has been evacuated after officials say they received a bomb threat claiming that three packages had been left inside a parking garage.

According to airport spokesman Rich Johnson, someone called the airport making a "very specific" threat, but did not elaborate.

Passengers were immediately told to exit onto the tarmac and that arriving planes should stay parked away from the gates.

According to WOAI News, Johnson says the evacuation order was called at 2:35 p.m. CST. He didn't immediately know how many flights are affected or how many passengers were inside the terminal at the time.

San Antonio police and several federal agencies are investigating the threat and asking everyone, including media, to stay away from the airport.
