More on Foxnews just now:

More flights may be canceled, all would be flights originating in Europe (could also include a US airline, which flies internationally, they didn't name it) and headed for the following US cities:

Newark, Washington, Miami, Los Angeles -- I think they mentioned a couple of other cities, I should have listened, instead of starting to type and missed it.

They also said, there is concern that the terrorists may plant a radiological bomb on one of the planes.
