Military police conducting operation at western border of Uri finish the job (3,2)
I believe the answer is:
mop up
'finish the job' is the definition.
'mop up' can be an answer for 'finish' (mopping up is a kind of finishing). I am not certain of the 'the job' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for mop up that I've seen before include "Finish off a task, clean away remnants" , "Kill (enemy stragglers)" , "take care of" , "Swab" , "Clear away, dispose of" .)
