Break apart Croatian port (5)

I believe the answer is:

split

I believe this is a double definition.

'break apart' is the first definition.
(I've seen this before)

'croatian port' is the second definition.
(I've seen this before)

(Other definitions for split that I've seen before include "Croatian destination" , "Bifurcate" , "Cleave or break up" , "shop" , "Riven; schism" .)

I've seen this clue in The Sun.
