Palestinian security services arrested two suspects Sunday evening believed to be involved in the shooting incident near Ramallah. A 10-year-old boy and a cab driver were wounded in an attack perpetrated Sunday morning by the Martyr Masoud Iyad Cell, part of Fatah's al-Aqsa Marytrs' Brigades. The group said it was in retaliation for a Jewish terrorist attack in the Israeli Arab town of Shfaram, which killed four. Two al-Aqsa terrorists were arrested on suspicion of involvement in the attack in the refugee camp of Jalzoun by the Palestinian Authority's Preventative Security force. PA security found the shooters' car abandoned in the camp. PA won't tolerate 'irresponsible' parties The two are not wanted by the government, a PA security services source told Ynet. However, he refused to say if they were tracked down with Israeli help. Instead, he said that the PA would do everything in its power to stop any violation of the cease-fire, to which all Palestinian factions have committed themselves. "We will not allow large political processes to be damaged by marginal, irresponsible parties in Palestinian factions," he said. Over the course of the evening, there were shooting incidents in there were of Qalqilya and village of Silat a-Dahar. In both cases al-Aqsa took responsibility.
