The Hamas-dominated Palestinian Legislative Council Thursday passed a law that makes any concessions on Jerusalem illegal and defines such concessions as a crime of high treason. Many Fatah legislators made it known that they too support the law, which states that Jerusalem is a Palestinian, Arab and Islamic city. The new law still requires the approval of Mahmoud Abbas, said Ahmed Bahar, acting speaker of the PLC. The law is intended to embarrass Abbas and ties his hands on the eve of the resumption of Israeli-Palestinian negotiations on core issues, including the future status of Jerusalem. Hamas officials said Abbas would have no other option but to endorse the law.
