Saint broadcast short mass in Turkish city (8)
I believe the answer is:
istanbul
'turkish city' is the definition.
(city in Turkey)
'saint broadcast short mass' is the wordplay.
'broadcast' is an anagram indicator (letters scattered or cast around).
'short' means to remove the last letter.
'mass' becomes 'bulk' (bulk can mean a mass of something).
'bulk' with its final letter removed is 'bul'.
'saint' is an anagram of 'istan'.
'istan'+'bul'='ISTANBUL'
'in' is the link.
(Other definitions for istanbul that I've seen before include "Eurasian city" , "City - lab units (anag)" , "Modern Byzantium" , "foreign city" , "Port and former capital of Turkey" .)
