Wind, more vicious round centre of Mogadishu (7)
I believe the answer is:
meander
'wind' is the definition.
('meander' can be a synonym of 'wind')
'more vicious round centre of mogadishu' is the wordplay.
'more vicious' becomes 'meaner' (I've seen this in other clues).
'round' means one lot of letters goes inside another.
'centre of' means to look at the middle letters.
The middle letter of 'mogadishu' is 'd'.
'meaner' going around 'd' is 'MEANDER'.
(Other definitions for meander that I've seen before include "Renamed (anag)" , "Aimless course" , "circuitous route" , "Dear men (anag) - wander" , "(Of river) wander" .)
