Belgium has remained on Level 3 - meaning that an attack "is possible and likely" - since the deadly suicide- bomb attacks on the Brussels airport and subway on March 22 last year.
Belgium's Crisis Center said today that "Level 4 is not determined in any of these assessments at this time," and that it has "no information indicating that a terrorist attack might be planned."
Top of the scale Level 4 indicates a threat of imminent of attack.
