I fled Middle Eastern country (4)
I believe the answer is:
iran
'middle eastern country' is the definition.
(country in the Middle East)
'i fled' is the wordplay.
'fled' becomes 'ran' (ran away).
'i'+'ran'='IRAN'
(Other definitions for iran that I've seen before include "Previously known as Persia" , "Country of western Asia" , "Islamic republic on the Persian Gulf" , "Formerly Persia" , "Iraq's neighbour" .)
