Belgian Congo today (5)
I believe the answer is:
zaire
'belgian congo today' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for zaire that I've seen before include "Central African country's former name" , "renamed African area" , "Former African country name" , "Previous name of African state, achieved independence from Belgium in 1960" , "Previous name of Congo" .)
