Police investigating the Paris terror attacks in November are questioning three people…in Brussels.
It follows a house search there, in the southern neighbourhood of Uccle.
Also on Tuesday, new developments were announced in the inquiry into the March 22 attacks in the Belgian capital.
A further two men have been charged with offences including ‘terrorist murder’.
They are suspected of links with the rental of a property in Brussels thought to have been used as a safe house ahead of the bombings, in which 32 people were killed.
Prosecutors have identified the pair only as Smail F., born in 1984, and Ibrahim F., born in 1988. Local reports suggest they may be brothers.
That brings to six the total of suspects caught and charged since late last week in connection with the Brussels suicide attacks.
Among them is Mohamed Abrini, who investigators say has confessed to being the so-called ‘man in a hat ‘ who deposited a bomb at Zaventem airport.

Abrini is also wanted in connection with November’s attacks in Paris that killed 130 people.
The prime suspect in those shootings and suicide bombings, Salah Abdeslam, was arrested on March 18 in Brussels, four days before the attacks there at the airport and on a rush-hour metro train.
The Belgian newspaper Het Nieuwsblad on Tuesday published what is presented as the ‘first photograph’ of Abdeslam in prison, in which he is shown with longer hair than in previous pictures and with a beard.
