Yesterday, a delegation of Gulf Arabs - there is disagreement as to whether they were from the UAE or Oman - visited the Dome of the Rock on the Temple Mount.
Mahmoud Abbas' Fatah party issued a statement that they consider any Arabs who visit the Al Aqsa Mosque compound without coordinating the visit with them to be no more legitimate than the Jewish "settlers" visiting the site. They used to claim that Al Aqsa was the heritage of all Muslims; now they are saying that "sovereignty over the holy sites is Palestinian and only Palestinian."
Palestinian Muslims on the Mount were upset by the delegation, and some of them harassed and insulted them, which had to be protected by Israeli police. Here one says "may Allah's curse be upon your sheikh" and calls them "impure."
Jews are protecting the right of Muslims to worship - in the holiest Jewish spot on Earth - and Palestinian Muslims are the ones trying to take away that right.
If Arabs are still on the fence about what to think about Palestinians, this should clinch it.
