Police officers survey the wreckage of Pan Am Flight 103 in Lockerbie, Scotland, in December 1988.

President Bush signed an executive order Friday restoring Libyan immunity from terrorism-related lawsuits and dismissing pending cases over compensation as part of a deal reached this summer. David Welch, the top U.S. diplomat for the Middle East, who negotiated the agreement, called Libya's rehabilitation from a terrorist nation to a U.S. ally "historic."Payment is part of multitiered plan to normalize relations between the two countriesTensions go back to attacks on Pan Am 103, German disco, U.S. airstrikesLibya now exempt from legislation allowing victim compensation from frozen assetsDeal ends Libyan liability in terror cases, paves way for U.S. investment
