Many people have been killed or seriously injured in terrorist attacks at Brussels international airport and a city metro station, Belgium’s PM says.
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 Maelbeek metro station. The airport and whole transport system are closed.
The attacks come four days after Salah Abdeslam, the main fugitive in the Paris attacks, was seized in Brussels. Belgium has now raised its terror threat to its highest level.
Prime Minister Charles Michel called the attacks “blind, violent and cowardly”, saying they were a “tragic moment in our country’s history. I would like to call on everyone to show calmness and solidarity”.
The Belgian prosecutor said it was “probably a suicide bomber” who struck the airport.
Belgian broadcaster VRT said 13 people were killed at the airport, with at least 35 people severely injured.
Some reports from the metro station speak of at least 10 deaths, but again there is no official confirmation.
The Belga news agency reports that shots were fired and shouts in Arabic were heard before the two explosions at the airport.
