Without knowledge of peacekeepers a conflict heads east (7)
I believe the answer is:
unaware
'without knowledge' is the definition.
(I've seen this before)
'peacekeepers a conflict heads east' is the wordplay.
'peacekeepers' becomes 'un'.
'conflict' becomes 'war' (war is a kind of conflict).
'heads' suggests taking the first letters.
The first letter of 'east' is 'e'.
'un'+'a'+'war'+'e'='UNAWARE'
'of' is the link.
(Other definitions for unaware that I've seen before include "Uninformed" , "Ignorant, oblivious" , "In the dark" , "Not conscious of what is going on" , "Lacking knowledge (of a situation or fact)" .)
