A 24-year-old bus driver, Najibullah Zazi, and his father Mohammed, 53 -- both Afghan natives -- were arrested in the western US state of Colorado late Saturday, the US Justice Department said.
Ahmad Wais Afzali, 37, also from Afghanistan, was later arrested in New York, the department said in a statement.
"Each of the defendants has been charged by criminal complaint with knowingly and willfully making false statements to the FBI in a matter involving international and domestic terrorism," the statement said.
Najibullah Zazi, who is a legal permanent resident of the United States, and Mohammed Zazi, a naturalized US citizen, are set to appear in a Colorado federal court on Monday.
On the same day Afzali, also a legal permanent resident, is scheduled to stand before a federal court in New York.
If convicted each man faces eight years in prison.
"The arrests carried out tonight are part of an ongoing and fast-paced investigation," said David Kris, assistant attorney general for national security, adding that officials had no specific information on any alleged plot.
