On Friday morning, at around 11:50, emergency services were called to the 13th floor of the European Commission building – where President Ursula Von Der Leyen's office is.
While some mistook the incident for a fire, the Brussels Fire Brigade confirmed to The Brussels Times that the Commission had in fact received an envelope containing suspicious white powder.
According to Walter Derieuw, a spokesperson for the Brussels Fire Brigade, only one individual came into contact with the powder and has not presented any medical symptoms.
The situation is now said to be "under control," and the building is not currently being evacuated. Furthermore, Civil Protection is on-site to analyse the powder.
