Nagasaki marks 75 years since atomic bombing

The Japanese city of Nagasaki on Sunday commemorated the 75th anniversary of its destruction by a US atomic bomb, with its mayor and the head of the United Nations warning against a nuclear arms race. Nagasaki was flattened in an atomic inferno three days after Hiroshima -- twin nuclear attacks that rang in the nuclear age and gave Japan the bleak distinction of being the only country to be struck by atomic weapons. Survivors, their relatives and a handful of foreign dignitaries attended a remembrance ceremony in Nagasaki where they called for world peace.
