The main airport in the Belgian capital has been shut down after two explosions were reported in its departure hall.
Police said at least one person died in the March 22 blasts at Brussels' Zaventem airport, while several others were injured.
The cause of the explosions is unknown.
The Belga news agency said shots were fired and words in Arabic shouted before the explosions.
Reports said no flights were leaving or arriving at the airport, and rail transport to the facility has been halted.
Images on RTBF’s website showed smoke rising from the terminal building, where the windows have been shattered.
The development comes four days after the capture in Brussels of Salah Abdeslam, the prime surviving suspect for the November Paris attacks in which 130 people were killed.
