A bar's reconstructed for port in Iraq (5)
I believe the answer is:
basra
'for port in iraq' is the definition.
(I've seen this before)
'a bar's reconstructed' is the wordplay.
'reconstructed' is an anagram indicator.
'a'+'bars'='abars'
'abars' anagrammed gives 'BASRA'.
(Other definitions for basra that I've seen before include "Iraqi town" , "Iraq's main port" , "Iraqi port on the Shatt-al-Arab waterway" , "Middle Eastern city" , "Chief port of Iraq" .)
