This just in ... Arafat's Fatah organization is now threatening to attack American targets. They're also threatening "1970s-style" operations - which presumably means skyjackings (report).

Update: Haaretz says that the contents of the relevant pamphlet were broadcast on al-Jazeera and attributed to Fatah, but that Fatah has denied responsbility for the pamphlet (report). But regardless, Al-Jazeera has broadcast the message to all its viewers.
