Global body noted they're not kept under surveillance (10)
I believe the answer is:
unobserved
'not kept under surveillance' is the definition.
The answer and definition are not the same part of speech.
'global body noted' is the wordplay.
'global body' becomes 'UN' (United Nations).
'noted' becomes 'observed' ('observe' can be a synonym of 'note').
'un'+'observed'='UNOBSERVED'
'they're' is the link.
Can you help me to learn more?
(Other definitions for unobserved that I've seen before include "without supervision" , "behind closed doors" .)
