Countries in turmoil and so on (5)
I believe the answer is:
lands
'countries' is the definition.
('land' can be a synonym of 'country')
'in turmoil and so on' is the wordplay.
'in' indicates the answer is hidden within the clue.
'LANDS' can be found hidden inside 'turmoil and so on'.
(Other definitions for lands that I've seen before include "Obtains" , "See 21" , "Alights" , "Comes ashore" .)
