Funny Line in the Palestinian Papers

On p. 5 of  this document, in the context of a conversation about how to deal with the headache of Hamas in Gaza, Livni  quips:

We have a saying, too. When you want to curse someone you tell him "Go to hell" but we shorten it and say "Go to Gaza"

Livni is referring to the Hebrew equivalent of "Go to hell" - "lekh la-Azazel" which can indeed be shortened to "lekh le-Aza."
