We lived just outside Brussels in the early 1980s.
We flew in & out of Zaventem airport, and drove past it often.
I had several friends who lived in the Schaarbeek/Schaerbeek neighborhood.
We used or passed through the Maalbeek/Maelbeek and Schuman stations many times.
Watching the BBC reports, I think I recognize the street where the follow-up raids took place; if I'm right, it's just one block over from where one of my best friends lived.
We're hurting with you, Brussels.
