Broadcaster I attack, one in African country (8)
I believe the answer is:
djibouti
'african country' is the definition.
(country in Africa)
'broadcaster i attack one' is the wordplay.
I cannot really see how this works, but
'broadcaster' could be 'dj' (dj is a kind of broadcaster) and 'dj' is found within the answer.
'i' is found in the answer.
'attack' could be 'bout' (I've seen this before) and 'bout' is located in the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
No letters remain.
This explanation may well be incorrect...
'in' is the link.
(Other definitions for djibouti that I've seen before include "foreign port" , "part of Africa" , "East African republic" , "Country in the Horn of Africa" , "Republic between Eritrea and Somalia" .)
