NEW YORK — Two men were arrested today in the investigation of a bomb plot targeting New York City that previously led to charges against a Colorado airport driver.

The arrests in New York of Adis Medunjanin and Zarein Ahmedzay were part of "an ongoing investigation" by the Joint Terrorism Task Force, according to Special Agent Richard Kolko, who declined to comment further.

There were no immediate details on the charges against the men, according to Kolko and Robert Nardoza, a spokesman for the U.S. attorney's office in Brooklyn.

Nardoza said the men were expected to appear in court later today.

Medunjanin's attorney said the FBI seized his client's passport on Thursday. Robert C. Gottlieb said the search warrant indicated the passport was sought as part of an investigation into a conspiracy to use weapons of mass destruction.

The Colorado airport driver, Najibullah Zazi, previously pleaded not guilty to that charge. He is accused of getting al-Qaida training to build homemade bombs to attack New York City.
