French President Emmanuel Macron must say whether his country was to blame for an Italian air disaster that killed 81 people more than 40 years ago, former Italian Prime Minister Giuliano Amato said on Tuesday. Italian judges have said in the past that a missile likely downed the DC-9 civilian aircraft near the island of Ustica on June 27, 1980, but have been unable to identify who was responsible for one of the darkest mysteries in Italy's postwar history. In a weekend interview with La Repubblica newspaper, Amato said he believed that the aircraft, belonging to the now-defunct domestic airline Itavia, was probably shot down accidentally by a French jet during a botched attempt by France, the U.S. and NATO to kill the then-Libyan leader Muammar Gaddafi while he was flying over Italy.
