In pieces, like foreign articles (7)
I believe the answer is:
asunder
'in pieces' is the definition.
(asunder means torn apart)
'like foreign articles' is the wordplay.
'like' becomes 'as'.
'foreign articles' becomes 'under'.
'as'+'under'='ASUNDER'
(Other definitions for asunder that I've seen before include "separately" , "(Split) apart" , "(Break) apart" , "Let no man put -" , "(Rent) apart" .)
