Police raided seven homes in Brussels’s infamous Molenbeek district, home to the city’s largest Muslim population and the perpetrators of the March 2016 bombings which killed 32 people, and the Flemish towns of Geraardsbergen and Mechlen.
A judge specialized in terrorism matters had asked for the home searches to be carried out. Eight people were detained but no weapons or explosives were found.
The news was first reported by newspaper DH. Prosecutors did not give any further detail, but said the case was not connected to the November 2015 Paris attacks or the March 2016 Brussels bombings.
