Sand in storm coming round united country (5)
I believe the answer is:
sudan
'country' is the definition.
(I know that Sudan is African country)
'sand in storm coming round united' is the wordplay.
'in storm' indicates an anagram (I've seen this in other clues).
'coming round' is an insertion indicator.
'united' becomes 'U' (as in Man U, Manchester United).
'sand' anagrammed gives 'sdan'.
'sdan' enclosing 'u' is 'SUDAN'.
(Other definitions for sudan that I've seen before include "Country divided by the Nile" , "Region of Africa" , "Country bordering the Red Sea" , "Sun ad for the African state" , "Country south of Egypt" .)
