Drink fizzy pop in Syrian city (6)
I believe the answer is:
aleppo
'syrian city' is the definition.
(I've seen this in another clue)
'drink fizzy pop in' is the wordplay.
'drink' becomes 'ale' (type of beer).
'fizzy' indicates anagramming the letters (I've seen this in other clues).
'in' indicates putting letters inside.
'pop' anagrammed gives 'ppo'.
'ale' placed into 'ppo' is 'ALEPPO'.
(Other definitions for aleppo that I've seen before include "Tomorrow" , "City in Syria - lop ape (anag)" , "Lap Poe around the Syrian city" , "Foreign city" , "War-torn city of Syria" .)
