Belgian police have identified a flat in Brussels where they believe one of the Paris jihadists hid after the 13 November 2015 attacks.
Traces of explosives and a fingerprint of fugitive Salah Abdeslam were found in an apartment in the Schaerbeek district.
The apartment had been rented in a false name, that might have been used by a person already in custody.
The BBC's Gavin Lee says investigators believe a significant amount of the planning for the Paris attacks was done from Brussels.
