There has been widespread condemnation of today's attacks.
Secretary General of the United Nations Ban Ki-moon says they have "struck at the heart of Belgium and the centre of the European Union", while President of the European Commission, Jean-Claude Juncker, says 'the European Union and its Institutions stand united in the face of terrorism'.
Here at home President Michael D. Higgins is leading tributes saying 'these actions must not undermine the will of all Europeans to live and work together, while acting Taoiseach Enda Kenny says today's events are 'an attack on democracy'.
Foreign Affairs Minister Charlie Flanagan says Ireland stands in solidarity with the people of Brussels.
It has also been announced that the Irish flag will be flown at half-mast tomorrow and Thursday, out of respect for the victims of today's attacks and those who lost their lives in the tragedy in Buncrana on Sunday.
