Al Queda is desparate to solidify the tie between the Palestinian cause and their own cause. They've been pretty successful.

The killing of Hamas leader Abdel Aziz al-Rantissi in an Israeli air strike is particularly significant; it follows a recent shift by the United States that took Washington nearer to Israel's position on the occupation of Palestinian territories. With Israel pledging continued attacks against Palestinian leaders, the killing of al-Rantissi will be perceived as an act sanctioned by the United States, following Washington's April 14 policy announcement. That increases even further the risk of militant strikes against U.S. targets.
