Ends Lagos riots (5)
I believe the answer is:
goals
'ends' is the definition.
('goal' can be a synonym of 'end')
'lagos riots' is the wordplay.
'riots' indicates an anagram.
'lagos' anagrammed gives 'GOALS'.
(Other definitions for goals that I've seen before include "Aims" , "Objectives" , "Ends, targets" .)
