Belgium has charged a further two men with terrorist offences over alleged links with the rental of a property thought to have been used as a safe house ahead of the Brussels attacks, federal prosecutors said on Tuesday.
Four other suspects were picked up on Friday, including Mohamed Abrini, who investigators say has confessed to depositing a bomb at Brussels airport, and Osama Krayem, suspected of buying bags used by the bombers.
Abrini is also wanted in connection with November's attacks in Paris, which killed 130 people.
The March 22 attacks in Brussels killed 32.
Prosecutors identified the two men, who were charged on Monday, only as Smail F., born in 1984, and Ibrahim F., born in 1988. They did not say when the two were detained. Under Belgian law, suspects usually need to appear before an examining judge within 24 hours.
"They are charged with participation in the activities of a terrorist group, terrorist murders and attempts to commit terrorist murders, as a perpetrator, co-perpetrator or accomplice," federal prosecutors said in a statement.
Police raided the suspected safe house, in the central Brussels district of Etterbeek, on Saturday, but found no weapons or explosives.
