Libya and lawyers for families of the 1988 Pan Am 103 bombing victims have signed an agreement to set up a $2.7 billion compensation account.
The lawyers say they and Libyan officials signed the deal Wednesday in London.
Under the arrangement, Libya is now required to send a letter to the U.N. Security Council taking responsibility for the bombing over Lockerbie, Scotland that killed 270 people. The deal also calls for Libyan officials to renounce terrorism and agree to cooperate with any further Lockerbie investigation.
If Libya fulfills the terms, the U.N. Security Council will vote to lift economic sanctions imposed in 1992.
It is not yet clear if or when the United States will consider ending its own separate sanctions against Libya or remove it from the list of state sponsors of terrorism.
Wednesday's signing comes a day after Libya agreed to the terms of a deal with the United States and Britain to take responsibility for the bombing.
A U.S. State Department official told VOA that if the families accepted the Libyan deal, it would also be acceptable to the Bush administration.
Pan Am Flight 103 blew up over Lockerbie, Scotland in December, 1988, killing all 259 people on board and 11 people on the ground.
A Scottish court sitting in the Netherlands convicted a Libyan agent in 2001 for planting a bomb on the plane. He is serving life in prison. A second agent was acquitted.
