'Welsh fans upset' — it may interrupt a programme (9)

I believe the answer is:

newsflash

'it may interrupt a programme' is the definition.
(I know that many newsflashes sometimes interrupt television programmes)

'welsh fans upset' is the wordplay.
'upset' is an anagram indicator.
'welsh'+'fans'='welshfans'
'welshfans' anagrammed gives 'NEWSFLASH'.

(Other definitions for newsflash that I've seen before include "Bulletin" , "Dramatic announcement" , "Brief report" .)

I've seen this clue in The Guardian.
