The justice secretary in Scotland who released convicted Lockerbie bomber Abdel Basset Ali al-Megrahi on compassionate grounds says the man broke a promise not to celebrate his homecoming. Kenny MacAskill defended his decision to free al-Megrahi, but said the bomber showed "no sensitivity" to the families of his victims. He called the celebration that greeted the bomber, which included some Scottish flags waving, “a matter of great regret,” and said he had been promised the felon's return would be "low-key." Prime Minister Gordon Brown is expected to urge Libya on Tuesday to cease their celebrations. The Libyan government defended its actions, insisting that the celebration “is something that can’t be understood by people in the West.” Libyan officials have bragged that al-Megrahi would be the “main guest” at a celebration on Tuesday marking the 40th anniversary of Colonel Muammar Gaddafi’s seizure of power.
