Homeland Security secretary Janet Napolitano told CNN's Candy Crowley there was no evidence that an attempt to blow up a Detroit-bound plane was part of a larger terror plot. "Right now, we have no indication that it's part of anything larger, but obviously the investigation continues," said Napolitano.

From Agence France-Presse:

"This was one individual literally of thousands that fly and thousands of flights every year. And he was stopped before any damage could be done," she said, praising how "effectively" passengers, crew and the global aviation sector responded.

Napolitano also warned that it would be "inappropriate to speculate" that Al-Qaeda trained Abdulmutallab and sent him on a suicide mission to blow up the Amsterdam-Detroit flight with 290 people aboard.

"Right now that is part of the criminal justice investigation that is ongoing, and I think it would be inappropriate to speculate as to whether or not he has such ties," Napolitano told CNN, referring to Umar Farouk Abdulmutallab, who has been charged with trying to blow up a Northwest flight on Christmas Day as it approached Detroit.

Unnamed administration officials told US media in the aftermath of the thwarted attack that Abdulmutallab had confessed to traveling to Yemen and receiving training by Al-Qaeda there.
