Block article's description of a fragmented region (6)

I believe the answer is:

balkan

'description of a fragmented region' is the definition.
(as in the Balkan Peninsula)

'block article's' is the wordplay.
'block' becomes 'balk' (balk can mean to block or resist).
'article' becomes 'an' (indefinite article).
'balk'+'an'='BALKAN'

(Other definitions for balkan that I've seen before include "Of SE European area" , "Such as Serbia, Kosovo" , "As Kosovo, Albania, etc" , "The -- peninsula contains Greece, Albania, etc" , "Large peninsula in southeastern Europe" .)

I've seen this clue in The Guardian.
