Abdelbaset al-Megrahi, convicted in the 1988 Lockerbie bombing, died in Libya on Sunday at age 60, according to his brother. Two hundred seventy people were killed in the attack, and in 2001 Megrahi was convicted by a court in the Netherlands. In 2009 he was released from Scottish prison after a cancer diagnosis gave the bomber months to live. Upon returning to his home country of Libya, Megrahi was welcomed by then-ruler Muammar Gaddafi. Despite calls for the bomber to be extradited to the United States or the United Kingdom, leaders refused after toppling the dictator.
