Temporary ceasefire (5)
I believe the answer is:
truce
'temporary ceasefire' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for truce that I've seen before include "Agreement to stop fighting temporarily" , "Cuter (anag.)" , "Peace agreement" , "Cruet (anag.)" , "Suspension of hostilities" .)
