The positive atmosphere that prevailed between Fatah and Hamas following Operation Pillar of Defense and the U.N. vote in favor of upgrading the Palestinians’ status appeared to have ended Thursday, December 27, as the two rivals resumed their verbal attacks on each other, The Jerusalem Post reported. The new crisis erupted after Fatah cancelled celebrations in the Gaza Strip scheduled for the end of this month to mark the 48th anniversary of its founding. Fatah officials in Gaza said they had decided to cancel the events because the Hamas government would not allow them to hold rallies in two of Gaza City’s main squares. Hamas has banned Fatah from holding major rallies in Gaza ever since the terrorist group took control of the area in 2007. Fatah, in contrast, recently permitted Hamas to celebrate its anniversary in several West Bank cities for the first time since that year.
