The minors, aged 15-17, were questioned by a judge in Dendermonde, East Flanders, who reported concrete plans to attack a concert hall in Brussels “within a few weeks.”
The prosecutor’s spokesperson could not confirm the name of the target to POLITICO, but local media cited Le Botanique, a cultural center and music venue in the center of Brussels where concerts attract hundreds of spectators.
According to Belgian media, the suspects belong to a jihadist movement; the spokesperson declined to comment on that information.
