officials said. Interior Ministry spokesman Khaled Abu Hilal dismissed the shooting as a random attack and denied that the target was Siyam. The men, driving in a nearby car, apparently shot at a car in the motorcade, but not at the vehicle carrying Siyam, he said. The incident marks yet another escalation in the tense relations between Fatah and Hamas; Palestinian security officials are continuing to protest over unpaid salaries for the second consecutive day. Hamas blames Fatah for being the driving force behind the protests.
