Risk territory (7)
I believe the answer is:
siberia
'risk territory' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for siberia that I've seen before include "a place often very cold" , "Vast Asian region of Russia" , "Russian far-east" , "chosen by Putin for no-frills travel?" , "Region to which Russian and then Soviet governments sent those considered disloyal" .)
