Abdel Baset al-Megrahi, a Libyan intelligence officer who was the only person ever convicted in the 1988 Lockerbie bombing, died Sunday nearly three years after he was released from a Scottish prison to the outrage of the relatives of the attack’s 270 victims. He was 60.

Scotland released al-Megrahi on Aug. 20, 2009, on compassionate grounds to let him return home to die after he was diagnosed with terminal cancer. At the time, doctors predicted he had only three months to live.
