ALBANY, N.Y. (AP) — New York's U.S. senators are asking the Libyan transitional government to hold the convicted Lockerbie, Scotland, plane bomber fully accountable for his terrorist actions.Abdel Baset al-Megrahi (AHB'-dehl BAH'-seht AH'-lee ahl-meh-GRAH'-hee) was convicted and imprisoned in Scotland for the 1988 bombing of Pan Am Flight 103. The bombing killed 270 people, including 189 Americans.The Scottish government released al-Megrahi in 2009, believing he'd soon die of cancer. He was greeted as a hero in his native Libya and met with leader Moammar Gadhafi (MOO'-ah-mar gah-DAH'-fee), whose 42-year rule now teeters on the brink of collapse.Sens. Kirsten Gillibrand (KEHR'-sten JIL'-uh-brand) and Charles Schumer (SHOO'-mur) on Monday called for al-Megrahi to be returned to prison.Scottish officials say they want to contact him soon to ensure they'll still be able to oversee his parole.
