That was the synopsis given for this video on his Facebook page, as well as on the Fatah Facebook page (sorry, no subtitles, hopefully MEMRI or Palestinian Media Watch will excerpt this soon.)
Is he threatening worldwide terror attacks? Airplane explosions? Train station bombs? Sarin in the subways?
Well, the media will never ask him that, because he is from Fatah, and they are supposed to be the Good Guys.
Reporters just don't ask such awkward questions in today's cowardly news environment.
