From the PLO’s official WAFA news agency:

… “As people who suffer daily aggressions by Israel we understand the suffering of the injured and the families of those who were killed in cold blood. [So-called] Palestinians know the bitter taste of losing beloved ones as the Israeli army is killing civilians in Palestine almost by the hour.”

But then, without realizing it, they switched from comparing Israel and [Islamic State] to claiming that ISIS is, like Fatah terrorists, just reacting to Israeli crimes:

… “It is time to end the brutal Israeli occupation which breeds violence in the entire world.”
