Several people were killed in an explosion at Maelbeek metro station, Brussels, around 09:15 (08:15 GMT) on Tuesday. The metro station is less than a kilometre away from European Union buildings in the centre of the Belgian capital.
The blast came only an hour after two explosions ripped through Zaventem airport in Brussels.
The airport is currently on lockdown, with rail transport stopped and incoming flights diverted to Antwerp and other locations. Belgium has raised its terror threat to its highest level.
Brussels Mayor Yvan Mayeur said “about 20” people had died and more than 100 had been injured, 17 of them severely.
