Dutch F-16s escorted a Northwest Airlines flight bound for India back to Amsterdam's Schiphol Airport Wednesday, and authorities detained several passengers for questioning, an airport spokeswoman said.
The pilot requested permission to return as the aircraft was flying over Germany shortly after leaving Amsterdam, and asked for a military escort, spokeswoman Pamela Kuypers said.
Customs police were investigating the security alert, and airport authorities had no further information on what caused the alarm, she said.
The Dutch National Terrorism Coordinator's Office was informed, but said there was no cause to raise the nation's terror threat level, said spokeswoman Judith Sluiter.
