I'm a little stuck... Click here to teach me more about this clue!

'foreign capital' is the definition.
'Warsaw' can be an answer for 'capital' (capital of Poland). I'm unsure of the 'foreign' bit.

'hostilities cut' is the wordplay.
'hostilities' becomes 'war' (hostilities between two nations).
'cut' becomes 'saw' (sawing is a kind of cutting).
'war'+'saw'='WARSAW'

Can you help me to learn more?

(Other definitions for warsaw that I've seen before include "Largest city in Poland" , "Polands capital" , "European city (with a Convention for commercial flying)" , "Capital city on the Vistula" , "Poland's largest city" .)
