African seen in Mali by a Nigerian (6)
I believe the answer is:
libyan
'african' is the definition.
(Libyan is an example)
'in mali by a nigerian' is the wordplay.
'in' indicates a hidden word.
'LIBYAN' is hidden in the letters of 'mali by a nigerian'.
'seen' is the link.
(Other definitions for libyan that I've seen before include "One from Tripoli, perhaps" , "such as began in Benghazi" , "Citizen of Colonel Gadaffi's country" , "Native of Tripoli, say" , "Eg, native of Tripoli" .)
