Country, one with little river water (4)

I believe the answer is:

iraq

I'm a little stuck... Click here to teach me more about this clue!

'country' is the definition.
(I know that Iraq is Asian country)

I can't explain the remainder of the clue.

(Other definitions for iraq that I've seen before include "Middle Eastern country" , "Location of Baghdad" , "Present-day site of Mesopotamia" , "Basra's country" , "Middle East country" .)

I've seen this clue in The Times and The Sunday Times.
