Cooperation in Somalia is ongoing (7)
I believe the answer is:
liaison
'cooperation' is the definition.
(I've seen this before)
'in somalia is ongoing' is the wordplay.
'in' indicates a hidden word.
'LIAISON' is hidden in the letters of 'somalia is ongoing'.
(Other definitions for liaison that I've seen before include "Association" , "A contact or affair" , "Intermediary" , "Co-operation; love affair" , "An affair or mediation" .)
