Destruction of Capitol that's newsworthy (7)
I believe the answer is:
topical
'newsworthy' is the definition.
(I've seen this before)
'destruction of capitol' is the wordplay.
'destruction of' indicates an anagram.
'capitol' anagrammed gives 'TOPICAL'.
'that's' is the link.
(Other definitions for topical that I've seen before include "Relating to current affairs" , "About current events, of present interest" , "Of local interest" , "Dealing with current affairs" , "In the news" .)
