Rebel city destroyed by star (9)
I believe the answer is:
celebrity
'star' is the definition.
(star can mean a famous person)
'rebel city destroyed' is the wordplay.
'destroyed' indicates an anagram.
'rebel'+'city'='rebelcity'
'rebelcity' is an anagram of 'CELEBRITY'.
'by' acts as a link.
(Other definitions for celebrity that I've seen before include "target of paparazzo?" , "Well-known or famous person" , "Fame" , "Star" , "Famous person seen in rebel city" .)
