NEW YORK — The uncle of a Colorado airport driver charged in a terror plot against New York City has been indicted, two law enforcement officials said Wednesday.

The officials told The Associated Press that Naqib Jaji was indicted on a single felony charge and was arraigned in a sealed proceeding in Brooklyn two weeks ago. The charge wasn't specified.

The officials spoke to the AP on condition of anonymity because they weren't authorized to speak publicly on the matter.

Jaji's lawyer declined comment.

Jaji is the uncle of Najibullah Zazi, who was charged in September with plotting to attack New York City with homemade bombs. Zazi stayed at his uncle's suburban Denver home for several months last year.

Zazi bought beauty supplies in Colorado to make peroxide-based bombs, prosecutors have said. He tried to mix explosives in a hotel room in early September, then drove to New York to carry out an attack, possibly on the transit system, authorities said.

The indictment of Jaji was first reported Wednesday in The New York Times.

Two New Yorkers have also been charged in the case. The men, who attended a Queens high school with Zazi, were not directly linked to the foiled bomb plot. But authorities have said the two — Adis Medunjanin and Zarein Ahmedzay — traveled to Pakistan, where Zazi allegedly received training in explosives from al-Qaida.

All deny wrongdoing.

An indictment charged Medunjanin with receiving terror training and murder conspiracy. A federal prosecutor said he conspired to kill U.S. soldiers in Afghanistan after receiving military training from the terror network.

Cab driver Ahmedzay, 24, has pleaded not guilty to charges that he lied to the FBI during the probe about places he visited during the 2008 trip.
