Country united after the end of serious earlier rioting (6,5)
I believe the answer is:
sierra leone
'country' is the definition.
(I know that Sierra Leone is African country)
'united after the end of serious earlier rioting' is the wordplay.
'united' becomes 'one' (as in a phrase like 'we are one').
'after' is a charade indicator (letters next to each other).
'the end of' suggests the final letters.
'rioting' indicates anagramming the letters.
The last letter of 'serious' is 's'.
'earlier' anagrammed gives 'ierrale'.
's'+'ierrale'='sierrale'
'one' put after 'sierrale' is 'SIERRA LEONE'.
(Other definitions for sierra leone that I've seen before include "West African country, capital Freetown" , "W. African republic" , "West African nation" .)
