TwitterAnother explosion has now been reported at the Maelbeek metro station, close to EU institutions in Brussels.
The whole metro system has been closed, BBC reports.
The explosion comes less than an hour after two blasts at Zaventem airport left at least one person dead, according to police.
The blasts come four days after the capture of Salah Abdeslam in Brussels – the main suspect in the jihadist attacks on Paris in November. Belgium has now raised its terror threat to its highest level.
There are few reports yet about the metro blast.
More details soon.
