Tram and premetro services were interrupted too. De Lijn buses did not stop at the North Station either.
Rail traffic was suspended for an hour and resumed around 1:30PM. The hour long suspension will probably impact on the evening rush hour.
The Portalis building that houses the offices of the Brussels prosecutors too was evacuated. Two prisoners detained in the building have been moved elsewhere. Staff were allowed to return to their offices shortly after 2PM.
