LOL! I don't think unnamed sources are suspect in and of themselves, but they could at least narrow it down to a department that is in a position to know the truth of the matter, as in "a senior administration official" or "highly placed sources at the Pentagon". "Word in NYC diplomatic circles" and "one source familiar with the U.S. operations" just ain't gonna cut it.
First he says :
Diplomatic sources in Washington tell NewsMax's U.N. correspondent Stew Stogel that Israeli nationals are believed to be involved in the Iraq prison controversy.

OK, so they were visiting Washington... :o)
