At least 17 died and several were injured when explosions hit the departure hall of Brussels airport on Tuesday morning.
All flights at the airport have been suspended, the air traffic control service added.
Meanwhile another has been reported at the Maalbeek metro station in Brussels, which is just meters away from the Gare de Bruxelles-Schuman railway station.
No trains are currently running to or from Brussels Midi. Brussels customers are advised to postpone, and not come to station.
The blasts occurred four days after the arrest in Brussels of a suspected participant in November militant attacks in Paris that killed 130 people. Belgian police had been on alert for any reprisal action.
Social media showed pictures of smoke rising from the departure hall where all windows had been shattered by the blast. Passengers were seen running away down a slipway from the departure lounge.
Large amounts of smoke have been seen coming out of the metro station in the Belgian capital. Brussels’ transport authority says all metro stations in the city are being closed, Reuters reports.
Sky News television’s Alex Rossi, at the scene, said he heard two “very, very loud explosions”.
“I could feel the building move. There was also dust and smoke as well…I went towards where the explosion came from and there were people coming out looking very dazed and shocked.”
“The thinking here is that it is some kind of terrorist attack – that hasn’t been verified by any of the authorities here at the airport.”
Belgian media said rail traffic to the airport was suspended.
There was no immediate official comment on the cause of the attack.
The Mallbeek station is also near a number of important EU buildings such as Berlaymont building, which houses the EU Commission and the Council of the European Union.
Belgian authorities have raised the security alert to the highest level following blasts at the Zaventem Airport and Maalbeek Metro station.
A witness said: “The metro was leaving Maelbeek subway station when there was a really loud explosion. It was panic everywhere. There were a lot of people in the metro.”
Metro company STIB announced on Twitter that all Metro stations are now closed.
Emergency services staff carried injured people out of the station on stretchers, many of whom were seen to have torn and blood stained clothes.
A makeshift treatment center to give emergency medical aid to the wounded has been set up at a nearby pub.
The blast follows two explosions at Zaventem Airport in Brussels this morning shortly before 8am local time (7am GMT). At least 17 people have died and several others are seriously injured.
