VIDEO TRANSCRIPTION:

The Maelbeek metro station in Brussels reopens after an attack more than a month ago.

A bomb was detonated here during rush hour, killing 16. Suicide bombers had earlier struck a packed airport terminal.

Armed soldiers and security from Brussels' transport network now patrol the station.

But commuters say they are still in shock and still nervous.

"My heart is beating fast, I'm not feeling okay. It's quite emotional, very emotional."

(SOUNDBITE) (French) 63-YEAR-OLD ENGINEER, ROGER DUMBRUCK, SAYING:

"I tell myself it could happen anywhere, at any time. I'm wondering if I'm going to come back by car. Because it could happen at Central Station, it could happen ... who would have believed that it would be at Maelbeek? Why Maelbeek? Why at nine o'clock?"

The attacks in Brussels took place four months after Islamic State militants killed 130 people in Paris, sending shockwaves around Europe and across the world.

Links were identified between suspects in both attacks.
