Dozens of Belgians are going on trial accused of leading or being members of a terrorist organization that allegedly recruited fighters for jihadi groups in Syria.

Few of the 46 suspects are expected to attend the trial's opening Monday as they are either believed to be fighting in Syria or to have died in the country's civil war.

The case, one of the biggest-ever terror trials in Belgium, centers on the radical Muslim group Sharia4Belgium and its members.

The group was disbanded nearly two years ago. Prosecutors now want to prove it was a terror organization.

The prosecution's opening statements are scheduled Monday amid tight security in an Antwerp courtroom.
