Two explosions were heard in the departure hall of Brussels Airport at 07:57 Tuesday morning, in rows 4-5 (near the Brussels Airlines ticket office) and 11 (in the charter zone) of the registration area. The two bombs contained nails for a maximum damage to people; they were brought to the airport hidden in suitcases transported on trolleys. An unexploded bomb has been discovered at the airport. This third bomb has been destroyed by security services of the Army. A fourth bomb was discovered in the evening, which prompted police to re-establish a security cordon within the airport.
The Belgian prosecutor says the explosions were caused a suicide attack.
The airport has been evacuated. Last flight landed at Brussels Airport 08:22 local time. All air traffic is stopped and all arriving planes were diverted. Road traffic, trains and buses to/from the airport were at a halt. Airport remained closed for the whole day and also on Wednesday, in order to clean the rubble and prepare it for normal operation. However, some ferry flights will operate on Wednesday, either to bring back aircraft stranded in neighbouring airports, or to ferry aircraft to Africa for bringing back stranded passengers. Since the personnel has not yet been allowed inside the airport building where the experts of the scientific police are still at work, the airport will also be closed Thursday and Friday. Cargo traffic will be allowed on a limited basis.
People who were in aircraft have been gathered in hangars, where some tried to sleep on the floor, pending some additional security measures, before being allowed to leave either to go home or to hotels in the vicinity.
