Israel's Family Reunification Law allowed the Interior Minister to grant permanent resident status to West Bank Palestinians who have family members in Israel. A recent revision to this Law required that the Interior Minister "shall not grant" citizenship except in exceptional cases; recent additional modifications allow some citizenships, but limit based on age. In his comment to the Knesset Interior Affairs committee on July 19, 2005, Shin Bet Chief Yuval Diskin stated that "11% of those involved in terror attacks are Palestinians who entered Israel via the Family Reunification Law."
