A bar's wrecked in port (5)

Ross

I believe the answer is:

basra

Here is my best explanation:

'port' is the definition.
(I have seen 'Iraqi port ' mean 'basra' so perhaps 'port' could also mean 'basra')

'a bar's wrecked in' is the wordplay.
'wrecked' indicates an anagram.
'in' is an insertion indicator.
'bars' anagrammed gives 'bsra'.
'a' placed into 'bsra' is 'BASRA'.
