Armenian diplomats in Brussels and the delegation of the National Assembly have not suffered as a result of the blasts in the city, Spokesman for the Armenian ministry of Foreign Affairs Tigran Balayan said in a Twitter post.
Several explosions struck Brussels airport and the metro system, causing at least 13 deaths, Belgian media say.
Two blasts tore through the departures area of Zaventem airport shortly after 08:00 local time (07:00 GMT).
An hour later, an explosion hit Maalbeek metro station, close to the EU institutions. The airport and whole metro system have been closed.
The attacks come four days after Salah Abdeslam, the main suspect in the Paris attacks, was captured in Brussels.
The Belgian government has confirmed casualties at the airport but has given no numbers. The cause of the explosions is unknown.
Belgium has now raised its terror threat to its highest level.
