Addressed some Pakistan-occupied Kashmir editors at first (5)
I believe the answer is:
spoke
'addressed' is the definition.
('speak' can be a synonym of 'address')
'some pakistan-occupied kashmir editors at first' is the wordplay.
'at first' says to take the initial letters.
The initial letters of 'some pakistan occupied kashmir editors' is 'SPOKE'.
(Other definitions for spoke that I've seen before include "Rung" , "gave a lecture" , "gave address" , "Radius" , "Radiating rod" .)
