Geostrategy-Direct.com: Dossier: Ziad Samir Jarrah - Links to mysterious hijacker may have triggered Abu Nidal's death by suicide

" Today, Arab intelligence sources believe they have the answer. They assert that Jarrah was not part of Al Qaida. Instead, he was lent by a secular Palestinian terrorist group to help in the 9/11 attack in evidence that could provide the smoking gun of Iraqi involvement. "

This is a subscription only article, but demonstrates why I've purchased a subscription.  Not everything they mention turns out to be true, but they do seem to have a pretty good track record (WorldTribune, the publisher, and collaborator Middle East NewsLine are frequent sources of Matt Drudge).  The basic message, from an unamed Arab intelligence source, is that Ziad Samir Jarrah, raised Catholic, not at all interested in Islamic extremeism, and one of the Flight 93 hijackers has demonstrated links to a Palestinian terror group supported by Libya, the Fatah Revolutionary Council.  The leader of this group was none other than Abu Nidal, the Palestinian uber-terrorist that recently "commited suicide" in Baghdad.  Abu Nidal has been supported (in retirement) by Iraq since the Gulf War, and the contention of the article is that Iraq was covering tracks by staging Nidal's suicide after being tipped off that the US was building a case against Iraq through the ties to Jarrah. 

I have no idea if its true, since its all based on unamed sources.  I'm not going to cover the whole article, since its a subscription service, but I encourage you to subscribe and take a look for yourself.
