Fatah supporters on Tuesday withdrew from a rally in Gaza because protesters were flying factional flags instead of the Palestinian flag, a party official said. The rally was held to mark the Naksa, the 45th anniversary of Israel\'s occupation of the West Bank and Gaza. \"Fatah’s withdrawal along with some PLO factions from today\'s march is the result of not committing to holding the Palestinian flag which is the only flag that should be lifted in such a demonstration as agreed earlier,\" said Fayez Abu Eita, Fatah\'s spokesman in Gaza, in a statement. Hamas has governed the Gaza Strip since it ousted Fatah from the enclave in 2007.
