Germany supporting uprising in African country (5)
I believe the answer is:
niger
'african country' is the definition.
(Niger is an example)
'germany supporting uprising in' is the wordplay.
'germany' becomes 'ger' (I've seen this in other clues).
'supporting' says to put letters next to each other (in a down clue, some letters go below others).
'uprising' says the letters should be written in reverse.
'in' written backwards gives 'ni'.
'ger' after 'ni' is 'NIGER'.
(Other definitions for niger that I've seen before include "Landlocked W African republic" , "West African river and country" , "Part of Africa" , "one flowing through Mali" , "West African country, capital Niamey" .)
