Earlier this morning, two explosions took place at Brussels Airport.
There was later a third explosion at Maalbeek Metro station, in what Belgian prosecutors have now confirmed was a suicide attack.
All public transport in Brussels has now been closed as warnings of further explosions cause extreme concern and fear for safety.
Eurostar trains and flights to and from the Belgian capital have also been suspended.
An emergency number has been set up concerning the #Brussels blasts for those wanting to ask about friends and family - (0032) 02757300.
