Masked gunmen on Tuesday killed a man they suspected of having spied for Israel, members of the Al Aksa Martyrs' Brigades said. Jafal Abu Tzrur, 24, was shot dead by members of Al Aksa who suspected he had informed on three of their friends. The three were killed two and a half months ago during an IDF raid on the Balata refugee camp near Nablus. The group, linked to Palestinian Authority Chairman Mahmoud Abbas's Fatah movement, also said Abu Tzrur's girlfriend, who had been married to one of the Al Aksa men slain by Israel, was marked for death. The gunmen said Tuesday that they handed the woman, a mother of four, to her family, and that she was killed by her male relatives on grounds that she shamed her clan.
