Ask again about the city hit by an atom bomb (8)
I believe the answer is:
nagasaki
(Other definitions for nagasaki that I've seen before include "Japanese city suffering atomic attack in WW2" , "Second city to receive an atom bomb" , "Atomic bomb target, 9 August 1945" , "City A-bombed 1945" , "Japanese port, setting for Madame Butterfly" .)
