The federal Prosecutor’s office has opened an investigation into possible links between the Thalys shooter and jihadist organisations in Belgium, several Dutch-language papers reported on Monday.
The Belgian secret services don’t think Moroccan Ayoub el-Khazzani was a “lone wolf” extremist.
Investigators are trying to find out if he is part of a network based in Belgium, and if the attack was ordered. They also think he may have had help, at least in getting hold of the guns.
Investigators are also looking at a possible link between the attacks and threats made against Belgium last week.
