Missile in the news (8)
I believe the answer is:
bulletin
'the news' is the definition.
(bulletin is a kind of news)
'missile in' is the wordplay.
'missile' becomes 'bullet' (bullet is a kind of missile).
'bullet'+'in'='BULLETIN'
(Other definitions for bulletin that I've seen before include "Regular report" , "Short statement on the news as it comes in" , "Blunt lie in offical news statement" , "Short and regular up-date" , "News report" .)
