Belgian prosecutors say that DNA has identified an accomplice of captured Paris attacks suspect Salah Abdeslam.
The man is named as Najim Laachraoui, 24, still on the run. A statement said he had been using false ID and that his DNA had been found in houses used by the suspected jihadist network.
Abdeslam was captured in Brussels on Friday and is still being interrogated.
French President Francois Hollande will later meet relatives of some of the 130 killed in the 13 November attacks.
Meanwhile, Abdeslam's lawyer has denied Belgian media reports the suspect will become an informer in return for more lenient treatment.
So-called Islamic State (IS) said it was behind the Paris attacks.
