No MIVB services will operate across the Brussels Region on Sunday. Staff walked out after a staff member was attacked and killed on Saturday.
There will be no bus, tram or metro services operated by the Brussels local transport company MIVB, though other operators are running.
MIVB staff are seeking more safety measures and a meeting with Belgian Interior Minister Joëlle Milquet (Francophone Christian democrat). The meeting with the minister was initially scheduled to take place on Tuesday but has now been brought forward to Easter Monday.
The Brussels Prime Minister Charles Picqué (Francophone socialist) and a representative of the Justice Minister are expected to attend too.
The unions but also the MIVB management do not want to resume services as long as more extensive security measures have not been decided.
Brussels Transport Minister Brigitte Grouwels (Flemish Christian democrat) hopes services can be resumed as soon as possible: "I would like to ask the MIVB staff to express their concern, anger and sorrow in a different way."
Services are not expected to resume before Monday afternoon.
Drivers of the Flemish local transport company are wearing a black ribbon as a mark of respect for their dead colleague.
