There is a subtle, even open, difference.
The PA (Palestinian Authority) rules West Bank and Mahmoud Abbas of PA gave that award. Hamas is in Gaza.
The PA and Hamas don't see eye-to-eye and Egypt & KSA have tried several times to settle the difference but without any success.
In July, Egypt hosted Abbas & Haniyeh but as usual it failed. But, Haniyeh made a startling statement that the IDF didn't pay attention to.
He said that the window of opportunity against Israel was approaching as Israel was having internal dissensions and was weak therefore politically. “We are facing an exceptional stage in the course of the conflict, which requires us to think collectively and take exceptional decisions on how to confront [Israel’s] policies and rein in these extremists”, Haniyeh said.
Clear message there. {Much more prescient than what XJP talks of 'developments unseen in a century' etc.}
