Hmm, I would not even go into imagining such a "puzzling behavior".
The Foreign Ministry said in response that it had been informed by the consulate in New York that the FBI had arrested the five for "puzzling behavior." They are said to have had been caught videotaping the disaster and shouting in what was interpreted as cries of joy and mockery.
Sounds to me like a classic case of "man bites dog", and certainly not indicative of any concerted movement among Jews. But common throughout the Arab world.
