(AP Photo/ V.W. Vaughan) (Newser) – San Antonio International Airport was evacuated today after officials received a bomb threat alleging three packages had been left inside a parking garage. About 2,000 passengers inside a pair of terminals were temporarily herded onto the tarmac but eventually allowed back inside. Flights were put on hold briefly and roads to and from the airport closed. Authorities have not found anything suspicious, however.
