Unfortunately raised in Faisalabad (4)
I believe the answer is:
alas
'unfortunately' is the definition.
('alas' is used to express regret)
'raised in faisalabad' is the wordplay.
'raised' is a reversal indicator (going up in a down clue).
'in' indicates a hidden word.
'sala' is hidden within 'faisalabad'.
'sala' back-to-front is 'ALAS'.
(Other definitions for alas that I've seen before include "Cry of woe" , "Woeful expression" , "Expression of regret" , "More's the pity" , "Oh dear!" .)
