PORT-OF-SPAIN, Trinidad — A judge yesterday ordered three men extradited to America to face charges in an alleged plot to attack John F. Kennedy International Airport.

Chief Magistrate Sherman McNicolls rejected without comment a defense argument that the men could not be extradited on conspiracy charges under Trinidadian law.

A lawyer for defendant Abdel Nur, Richard Clarke-Wills, said he would appeal the ruling to the country’s High Court and a decision should take at least six weeks.

Attorney Rajiv Persad, who represents defendants Kareem Ibrahim and Abdul Kadir, said he had to speak to the men before deciding whether to pursue an appeal. Mr. Clarke-Wills said earlier that he had expected to lose the first round in the extradition case, and insisted that a confidential American government informant entrapped the men into plotting to attack the airport.

“If it were not for the intervention of this source you would not have these three men before the courts,” Mr. Clarke-Wills said before the ruling. “They had no terrorist aspirations or ideals … I have no doubt whatsoever this is a clear case of entrapment.”

Two of the suspects scoffed at the accusations before the hearing.

Messrs. Nur and Ibrahim spoke briefly to The Associated Press as police escorted them with Mr. Kadir into the court in downtown Port-of-Spain for the extradition hearing.

“It’s false,” Nur said. “It’s a setup. It’s a big setup by the drug dealers.”

Mr. Nur, who is from Guyana, was apparently referring to the confidential informant, a convicted drug dealer who taped conversations in which the suspects allegedly plotted to blow up a fuel pipeline that supplies the airport.
