TOKYO—The Japanese city of Nagasaki on Sunday marked its 75th anniversary of the U.S. atomic bombing, with the mayor and dwindling survivors urging world leaders including their own to do more for a nuclear weapons ban.
At 11:02 a.m., the moment the B-29 bomber Bockscar dropped a 4.5-ton (10,000-pound) plutonium bomb dubbed “Fat Man,” Nagasaki survivors and other participants stood in a minute of silence to honor more than 70,000 dead.
