Capital of Bosnia and Herzegovina (8)
I believe the answer is:
sarajevo
'capital of bosnia and herzegovina' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for sarajevo that I've seen before include "Capital of Bosnia-Herzegovina" , "Assassination here triggered WWone" , "Balkan capital" , "Place" , "Site of the assassination that sparked WW1" .)
