In our continuing coverage of tragic development in Brussels.
Reports indicate three bombs have caused severe damage and several deaths in Brussels.
Two explosions hit Zaventem airport at about 07:00 GMT, and another struck Maelbeek metro station an hour later.
The government has not confirmed casualty numbers. Brussels transport officials say 15 died at Maelbeek and media say up to 13 died at the airport.
Belgium has now raised its terror threat to its highest level.
The attacks come four days after Salah Abdeslam, the main fugitive in the Paris attacks, was seized in Brussels.
Prime Minister Charles Michel called the Brussels 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”.
