Belgian police have identified three safe houses used by key suspects behind the deadly Paris attacks, including presumed ringleader Abdelhamid Abaaoud.
The premises include a flat in Charleroi -- a town south of the capital Brussels where a major airport is located, as well as a house in the rural village of Auvelais near the French border and a flat in Brussels.
Belgian investigators found fingerprints from Abaaoud and suicide bomber Bilal Hadfi at the flat in Charleroi, as well as several mattresses.
No traces of explosives or weapons were found in either the Charleroi or Auvelais lodgings. Prosecutors said all of the accommodations were rented using false names and paid for in cash.
