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 an anagram (I've seen this in other clues).
'in' indicates putting letters inside.
'pop' with letters rearranged gives 'ppo'.
'ale' going within '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" .)
