One dead, several wounded at Brussels airport: police to Belga news agency
Two explosions were heard at Brussels Airport on Tuesday, Belgian media reported.
Images on the website of public broadcaster RTBF showed smoke rising from the terminal building, where the windows had been shattered.
The broadcaster said the blasts hit shortly after 8:00 am (0700 GMT) and that regional authorities had gone into emergency mode, with all flights in and out of the airport halted.
There was no immediate confirmation of the cause of the blasts or of any injuries, but RTBF cited a witness who said they had seen several wounded people.
Images showed people fleeing from the terminal building.
The blasts come days after the dramatic arrest in Brussels on Friday of Saleh Abdeslam, the prime suspect in the Paris terror attacks that killed 130 people in November, after four months on the run.
