Mayor Michael Bloomberg urged New Yorkers to keep calm on Monday in his first public comments about an alleged plot to blow up the John F. Kennedy Airport.
"You have a much greater chance of being hit by lightning than being struck by a terrorist," said Bloomberg.
But the confident mayor did urge vigilance, saying city residents should notify authorities when they see anything suspicious.
The mayor's call for calm echoed his actions over the weekend. After officials announced the foiled plot, the mayor did not turn up at a press conference to address the contained threat.
Four men, including Russell Defreitas - a former JFK air cargo employee - have been charged in the plot designed to set off explosives along a 40-mile jet fuel pipeline stretching from New Jersey to JFK.
Defreitas was arrested in Brooklyn on Friday. He remained in custody Monday in the federal Metropolitan Detention Center in Sunset Park without bail and is due back in court Wednesday.
Two other suspects were detained in Trinidad where the group had been trying to get financial support. They are expected to be extradited to the United States after court hearings.
The fourth suspect, identified as Abdel Nur of Guyana, is allegedly on the run in Trinidad.
U.S. intelligence services had been following the plotters since January 2006.
Reports say Defreitas recruited an FBI informant in the planned attack, and that he met with a radical group in Trinidad to get its support and financing for the plot.
On CBS's "Face the Nation," New York Police Commissioner Ray Kelly said officials busted the suspects as soon as they had enough evidence to prosecute.
