A U.S. House of Representatives panel is proposing limits on aid to Pakistan if it does not help the United States investigate a possible Pakistani support network for Osama bin Laden.

The U.S. investigation seeks to discover how the al-Qaida terrorist leader could have remained hidden in the Pakistani city of Abbottabad before U.S. special forces hunted him down and killed him in May.

The House Foreign Affairs Committee has propopsed a bill calling for limits on foreign aid to Pakistan unless the State Department certifies that Pakistan is fully assisting the U.S. in finding out whether bin Laden had help from Pakistani officials or others.

This would include giving U.S. officials direct access to bin Laden's relatives and the house in Abbottabad.

The bill would also limit aid to Lebanon, Yemen, and the Palestinian Authority if any members of terrorist groups are part of those governments. This includes Hamas in the Palestinian Authority and Hezbollah in Lebanon.

Committee head, Republican Ileana Ros-Lehtinen proposed the bill.
