Blood stains and broken glass were still seen at an entrance to Brussels' Maelbeek metro station after the deadly terrorist attack on Tuesday.
The entrance was relatively inconspicuous and was not cordoned off by the police, who have prohibited passage at the main entrances to the station.
Tuesday's blasts targeted Brussels' Zaventem airport and Maelbeek metro station. The blasts killed at least 34 people and injured more than 200.
