Our colleague Evan Lamos was in the metro between Arts-Loi and Maelbeek stations this morning when the explosion happened.
Evan is Multimedia Director at euractiv.com. He usually interviews people but roles were reversed this morning as he was himself being interviewed by dozens of international media for holding a live twitter feed from the metro after the explosion occurred.
Together with other passengers, he was evacuated on the tracks and he managed to get off at Arts-Loi station. You can follow Evan at @.
