International group's assistance is possibly implied (6)

I believe the answer is:

unsaid

I'm a little stuck... Click here to teach me more about this clue!

'possibly implied' is the definition.
'unsaid' can be an answer for 'implied' (I've seen this in another clue). I am unsure of the 'possibly' bit.

'international group's assistance' is the wordplay.
'international group's' becomes 'UN's' (United Nations).
'assistance' becomes 'aid' (synonyms).
'uns'+'aid'='UNSAID'

'is' acts as a link.

Can you help me to learn more?

(Other definitions for unsaid that I've seen before include "Not uttered" , "Tacit" , "not pronounced" , "omitted from speech" , "left to the imagination" .)

I've seen this clue in The Times.
